They're lumpy looking fat Hispanic chicks, probably in their mid-30s (could be far less, they age like milk). They're wearing stained clothes and yoga pants from Goodwill, and one of them has a little snot-nosed toddler trotting behind them. Are the two grown women related? Is the kid half-black? Who knows. It's one of life's many mysteries.
All you know for sure is that you've seen them before. Not them specifically, but this sort of "template" of customer. Everyone has.
They want an excessive amount of food, and a Happy Meal for their brat (which they'll mooch off of as well). Five minutes after they walk in, they'll both start yelling over each other at the pimple-faced cashier about not getting enough fries, but I'll have walked out the door and promptly forgotten about them by then.
