I once found a $20 counterfeited bill at walmart. I tried to buy some gum and the lady said it was fake. I still have it!
Use it on someone on the street selling food.
My aunt takes me to this event each year were she sells stuff, em and my cousins go out in the city after helping unpack and get £50. well one time she got a fake £10 note so we decided to try by ice cream with it, it worked and we got legit money back in the change =D
