Lesson: Always, always be kind to the wait staff. It's a tough job for little pay and dependent on tips, at least here in the barbaric states of America. Europe treats workers better.

I tend to be nice to anyone anyway, unless they are unpleasant to me.

If I didn't make it clear, the lesson wasn't directed at you, just a general observation. Have a better than awesome Sun-day.

I didn’t take it personally! But it just makes a difference not being offensive. Weird, huh?
