This was more of a dumb grudge than anything else, lol. I boycotted a local store because they refused to sell my fiance cigarettes, despite being of age and having ID - strictly because I was present. I was like 22 at the time so it would be perfectly legal, but I wasn't even buying them. I just didn't have my ID with me because I wasn't the one driving. He was denied service because I was in the immediate area. :/
But then we quit smoking so no reason to boycott anymore, haha.
