I've had some interesting experiences at my college's tutoring center, some people are just really bad at processing basic information. When I was the receptionist I had to tell a girl no less than ten times that we did not have a bio-chem tutor available at the exact second she was in there. We had a bio-chem tutor, we had one sceduled in a few hours, but no I cannot summon one right now.
Scheduling one-on-ones could also be a mess. When my friends was the main receptionist she ended up dealing with a guy (who was my personal horrorcow but that's another can of worms) who did not understand the concept of why you schedule an appointment.
The way one-on-one weekly tutoring appointments work is that the student sends and email to us to request one, we send them back an email with a tutor to meet with, a day, and a time. If they confirm that works, then they are expected to show up weekly at that time and day with that tutor. This guy sent an email requesting one-one-one sessions, my friend planned to have him with a certain tutor yadda yadda- He didn't send a confirmation back, but instead showed up at a random time on a random day and met with a random tutor his mom suggested him to meet. This tutor was doing drop-in only and wasn't available for appointments but agreed to help him for just that day.
My friend tried to send another email getting this guy to confirm but he never did, he just met with a random tutor again. He did this three times in a row and never got an actual one-on-one set up becasue he didn't understand the concept of confirming or even reading an email. Every tutor that had to work with him said he was nearly impossible to teach and it was like he wasn't even listening to what they were saying. There were also people who refused to tutor him for being creepy and looking like a serial killer but that's an additional can of worms.
