Visa commercials

There have been some Visa commercials that show people moving like clockwork in a food court or toy store and then someone pulls out a check/cash and then everything stops because it takes so long. The thing that kills me is that if it were up to the business they'd rather have Cash because everytime they process a credit card it costs the business at least 3%.

I myself enjoy using credit cards because I like a trail for business write offs...but the killer is that the one expense that I write off the most is the one service that is hard to get them to accept CC....A Taxi Cab.
