It would be extremely embarrassing if I got caught but I'll admit to sampling A grape or A cherry at the grocery store prior to purchasing to see if they are sweet or sour.......it's wrong, it's stealing and I shouldn't do it.
In the case of grapes and grapes only, when they are on sale, sometimes it's because they are sour. I have no problem with nibbling a grape or two to make sure they're edible.
I don't mind at all, my pet peeve are the sales ladies in dress shops that want to know your size, the style you are
looking for, the colour etc. These places I just walk out of and they are wondering these days why we shop online.
