I once ordered some food at the old Boston Chicken (now Boston Market), and the teenaged girl behind the counter, with the correct change showing on the register, took three times before she counted it out correctly.

It's gotten to the point where EVERY time I take out from somewhere, I have to open the bags or boxes and make sure everything I ordered is in there, before I drive back home. All these places hire children, give them no training except how to ring up the sale and swipe a credit card, and then they get the orders wrong EVERY time.
