Let's see if anybody agrees with me here that the following scenario is an example of rude behavior:

Someone comes into a fast food restaurant, usually alone (never more than two people), and proceeds to make up to five separate orders, which the cashier has to ring up individually and make change from five distinct piles of money. They're obviously buying food for their entire office, but you can imagine how much time it takes up, both for the cashier and for the unfortunate customers stuck behind this person or persons.

I say this is selfish. You should either a) call in the order, so the kitchen has a chance to prepare for it (then it can be waiting for you when you get there) or b) order everything as a single order. I know that the argument would be "but not everyone will get their change that way," but I say you should divide that up back at the office, on your own time, instead of wasting the time of those who are not in on your little office party and just want lunch in a reasonable amount of time.

Anyone agree with me on this? If you're a dedicated reader (and I know that both of you are out there, haha), shoot me an email and let me know your thoughts.
