You need to calm down, stop taking things so personally, and read.
Clearly you've never been in any sort of management situation where you control employment. If you had, you wouldn't even be discussing this. If your customers are uncomfortable, they won't spend money. If they don't spend money, you go out of business. I would venture to say that in a professional atmosphere, the vast majority would rather deal with a clean cut person.
Since I'm apparently, "One of those people", I'll let you in on a secret. I have piercings, and have a session for a tattoo set up for next month. NO WAY! The difference is mine are/will be discrete.
Once again, if I'm doing to hire someone to deal with customers, I'm going to hire the person who will best relate to ALL of them.
