No offense, but people that work in this industry and take stances like this make me chuckle. While, I do agree that a sponsor should use a business name that is somewhat generic, I also think that people that work in this industry should grow some balls (figuratively, of course) and realize that there is some amount of risk involved in this business. If you live in a small town where everyone is nosey, and you're uncomfortable with people knowing what you do, then maybe you shouldn't be in this particular business.
Or move, or something...
besides, how can you not enjoy seeing the teller get all uncomfortable, or interested? lol
