We saw this in the Biloxi Sun Herald.
Dear Annie: What do you think about a person who grabs every check at meals, golfing, etc., in order to put it on his credit card? We all have to pay him back our portion of the bill. The purpose of this is to get all the frequent flyer mileage. He then travels everywhere on this built-up mileage. He thinks his friends aren’t onto him. I think it’s greedy.

Dear Disgusted: Some people don’t mind giving cash and letting others reap the credit card benefit. If it bothers you, next time say, “George, it’s our turn to get the mileage. You can have the next go-round.” Or, of course, you can ask for separate checks.
