This morning I stopped at UDF for coffee (as I do every single morning). It costs $1.39. There was a huge line (understaffed) and I walked up and put my buck-thirty-nine on the counter, raised my coffee to show my intent and started to walk out. The manager had a near ballistic response and indicated that I should wait in the long line. I was sorely tempted to take my money and leave the coffee on the counter, but decided he was being a jerk and I would be late for a meeting if I stopped to engage him.

At restaurants it is OK to leave the correct amount on your table (with appropriate tip) and leave the premises. I have often done this at this same UDF. Have I missed something here?

When I worked a cash register (in a variety of establishments), the behavior I demonstrated this morning was viewed as appropriate, what has changed?
