What is the difference between the self-serve checkout machine at the grocery store and an actual cashier?
The machine has more personality. (Get it?? Because the teenagers who work there are so miserable??)
Then, the people behind me in line wouldn't put anything on the conveyor until the divider was down. WHAT'S UP WITH THAT??? It seriously bugs me. I know what I chose, and I'm not going to let the cashier scan stuff that isn't mine. PUT THE DAMN GROCERIES ON THE CONVEYOR WITHOUT THE DIVIDER!
