After a court proceeding this afternoon, where my wife accompanied me as a lark, we went to a good Mexican restaurant and ordered (and consumed) a big meal indeed, soup to nuts. Since I needed a smoke, I left my wife to pay the bill and went outside. When she joined me, reporting the tab, I was astonished at the low cost. Pressed, she explained that our margaritas were half-price since it was happy hour. Then, gasp, she proceeded to explain -- for the first time ever -- that our charming waiter had given us a 15% senior-citizens' discount based just on our looks! Talk about a mixed blessing.
