Was in a Wal-Mart very long ago that had feeder goldfish labeled as .99cents per fish. So I asked for 10 gave them a dime and said keep the change. They tried to argue that I owed them a dollar but I was successful in pointing out that they were not labeled as $.99. It did take two cashiers, a supervisor and the manager, but darn it I had a point to make and no where else to be.
Another one of the number things that bugs me. UAL awards there frequent flyers and award for flying 100,000 miles in a calendar year. They call it the 1K level. 1K is 1000 not 100,000 they should call it 100k. Bugs me every time I look at that card. I keep thinking that there is a reason they are financially messed up. they can't understand the difference between a thousand and one hundred thousand.
