If a character is doing it, as long as its out in the open, where the other players know about it. It isn't a taboo. Although you've got to ask about what will happen when the rest of the characters find out. The only negative impact IME was when a character was taking his pick from the loot before the rest of the party got there. Out of character we knew he was doing it, and it was in character, so that wasn't a problem. But he did it so often, he was becoming very wealthy , and spending it on magic items, that the rest of the party couldn't afford. Which started , at least from my POV a bit irritating.
