I agree with #1
Once a waitress never came back with change. I had to ask for it and she said "You want change?" in disbelief.
The total was $12 and I paid with a $20 bill. I have no idea why she expected an $8 tip on a $12 meal since it was just a plate lunch with included drink delivered on a tray and otherwise required no effort from her. To top that performance off, she was rude about actually bringing the change over.
Did you stiff her? I sure would have, because she tried to STEAL from you, so you should have done the same to her. It's only fair and morally right just as she had done onto you.
That's because she had ENTITLEMENT issues that she was ENTITLED to a tip and that's because she was TOO LAZY to get change from the bar, because apparently she didn't have much change on her.
