I’ll do that with some things that have to be weighed to get the price, but I don’t do that with strawberries that are already weighed out and priced, because if I decide I don’t want them, the next person’s going to be a strawberry short.I never did before, which I've seen some people do: sampling. Grapes are the same way. I'll try a grape or a strawberry to see how it tastes.
