Yeah that is an odd restriction... but I do know that my tattoo gets more odd looks and comments down south than it does anywhere else.
I remember once that someone said I shouldn't have a tattoo if I wanted to do something professional. My tattoo's on my upper left arm, though, so I just said that as long as I was wearing a long sleeved shirt, it'd definitely be covered...and it's still covered by short sleeved polo shirts.
He then said, "But what if you're playing golf or something, and the sleeve slips down and your tattoo shows?" ...I just said I'd cross that bridge if and when I got to it, haha.
