Is there anything worse than walking into a take-out place just a second or two behind another person only to have that person step up to the counter and pull out a list of things that several of his or her friends who aren't present want, resulting in all of the available staff ignoring you to work on the large order that Mr./Miss Inconsiderate coulnd't be bothered to phone in?
OK, maybe the same person doing it ahead of you at the drive-thru, and then sitting in front of the window thoroughly checking the order while your food grows cold.
In either case, those people need to be kicked. Kick them in the ass for the first offense, and in the head if they ever do it again.
Just a rant for the day, posted with a sigh as I remember when common courtesy was actually common and people had the sense not to do stuff like this.
