One time I decided to test whether these grocery story loyalty card XX cents off per gallon transactions were properly isolated, when my wife and I were both filling up vehicles at the same gas station at the same time. We both got the $0.50 discount per gallon with no problem. I'm sure there are lots of creative ways you can exploit the poor design of these things.
