I go out often with friends who "claim" to have no cash and want to put the meal on their credit card and I can then give them the cash. Since they get air mileage (and this has happened more than once, try every time and these are expensive meals) I have now taken to telling the waiter to put my portion on my credit card as I too have no "cash", I also get air mileage. it has taken me years to do this. I figure during that time I have paid for at least a third of several peoples trips to Europe. Anyone else in this predicament?
