Adventures in the Check-Out Line of the Creamery

Soo, I work at a grocery store. Every other day, I stand in the same two-square foot box with my register, checking out people's groceries, for four hours or so. Now that I've worked here for a while, I've been able to categorize all the customers that come in.

There are Nice Ones:

Awkward Ones:

You get your dad on the way home from work, stopping by to pick up some milk.

You get the elderly people, who are either very nice, or very mean.

There are some more awkward people:

And the ones that like the complain about everything:

Yeah, so next time you go grocery shopping, remember that the person at the register is a real person, with problems and a family and roommates and a facebook and a blog... and she probably blogs about customers like you... :P
