DH and I were at Epcot a week ago Saturday just for the day. On the way to see the British Invasion in England, we stopped and stood in a long, LONG line for beer at the kiosk outside of the pub. Did I say this line was long??
When we were finally the second in line, we heard the guy in front of us try to order two beers, one for his wife and one for himself. "Where's your wife?" asked the server. "We can only serve one beer per person." "She's in England, shopping." "Can you have her wave or something? I can't sell you 2 beers." "Gee, I don't know where she is." "Well, you'll have to go get her so that I can see her." "But I don't want to have to stand in this long line all over again."
At this point, my husband nudged me and said, "You should offer to let him buy you the beer." DH knew I'd already drank my limit (2 glasses of champagne!) and only wanted bottled water. So I stepped forward and said, "You can buy the extra beer for me!" The guy turned around, smiled, and said, "Oh look, here's my wife, right behind me!"

With that, the server sold him two beers, but the guy also waited to hear what we ordered (the beer for DH and water for me) and would literally not let us pay for it--he stepped back in front of us to pay for our drinks.
So we did a good deed and were rewarded with free drinks, to boot! We were really tickled!
