Ah yes the world of retail, one that is easy to get into but not easy to stay in. I've worked at a lot of different places and jobs, from Janitorial work to giving out flyers at streetlights, but I'l share my experiences in the retail world.
The Browser
If you don't know what a browser is in retail terms, it's someone who just comes in to look at things, spends like 1 to 2 hours in a store and just leaves without buying anything, now we all do it but browsers can tend to be worse. I used to work at a now defunct chain that sold computers back when I was in honk college. Mr.Browser walks in to my section and begins browsing computers, I start to chat him up about the latest models, new OS and what not, he gets interested and asks me some prices, I begin to show him different models and start to pile on other things (Printers,Anti Virus,Insurance,etc.) he's all excited and he asks me for a quote, this took about 3 hours of my time but it was gonna be a great sale, I bring him the quote just for him to say. "Thanks I'l look online to see if I find it cheaper." of course I had to keep the friendly fake smile and tell him it would cost a bit more since he would have to ship it and it would have just the basic warranty but he just left. I basically ended the day with low sales because of people like him.
The clueless lady
This one was at the same chain, I was again at my area when a older woman dressed in business suit comes in and starts to inquire about a computer, I start showing her different models and what not and she settles for one, I go to the back storage to get the item and bring it up to the front so she can buy it, she does and leaves, I'm happy because it was an easy sale, however an hour later she comes back screaming that I sold her something different, my manager calls for me and I go to greet her and ask what the problem is, she says I sold her something unnecessary and that I made her pay more and she wants her money back, I am confused since she only bought the computer and nothing else, so I ask her what is this unnecessary thing, well she opens the box and pulls out the actual computer. She says she doesn't need that just the computer. I try not to face palm when I realize what just occurred, she saw the price for the monitor and thought the Monitor was the computer, I explain to her this but she is still adamant that i'm just trying to scam her. "At work I only need to turn this on for the computer to work!" my manager is trying to hold his laugh in but he stays professional and plugs the monitor up so she can see it doesn't work and I shit you not the words that came out of her mouth "OH MY GOD YOU WERE GOING TO SELL ME A BROKEN COMPUTER!" in the end we just gave her the money back but after she left we started laughing and it became a joke.
The Daycare
Back after said chain closed, I found another job at small video game chain that sold old games (nes,snes,etc.) it was a nice place and I managed to snag a few things (Dreamcast that could play burned cd's, Snes,Mint Dragon Warrior NES game,etc) we had a few consoles for people to try out games (NES,SNes,Sega,N64,etc.) so it wasn't unusual for people to leave their kids around for a bit while they shopped at the target next door, most kids were well behaved and I would sometimes even get a sale when a kid got really interested in Mario Bros. However one night it was almost closing time about 9pm, it was just me and my manager and he wanted to leave early because it was his wife's birthday which I didn't truly mind. So at almost 9:30 this guy comes in with 4 kids and starts browsing the store, we are talking and then we notice the guy left, the kids are running and screaming playing hide and seek behind the shelves, fighting for controllers and getting angry when they lose, one of them even tries to reset the console (which is under key) by trying to force the lock open, my manager tells them to knock it off but they just keep going, it's now 10 and we wanna close and the dad is still nowhere to be found, so the manager goes into rage mode and just pushes the kids out of the store closing it, the dad comes back and starts screaming that he is gonna sue us for endangering his kids, how they could had been kidnapped and what not, security comes and we explain and soon the guy is asked to get out of the mall, we ended up closing at 12 am because they had spilled snacks and disturbed the cases and what not.
The console mom
This one day I'm working on the floor when this mother comes in, she wants to buy a game for her son's console, I ask her which and she says Halo, I'm happy to oblige and go get the game from the back, as it's customary we tell her the game's rating and what it contains, I ask what console it is he has and she says it's a PS2, I frown and tell her this game is for an Xbox and it won't work on a PS2, she gets upset and tells me she needs to buy it anyways. I explain they are different consoles made by different companies. "But they both use CD's!" she exclaims "Yes but they are made for different machines, it's like how a engine for a Ford won't fit a Toyota, they are both engines but made for different cars" she is still adamant and pull this jewel. "Well I have a friend who is a hacker and can hack the PS2 to play Xbox games" I look amused but I shrug, I sell her the game regardless, next day she comes back pissed that the game I sold her won't work.
