I think the place of employment has a lot to do with whether or not an employee should have visible body tats and jewellry.
Personally I don't like tats or piercings for myself (apart from one earing in each ear). I do think they look cheap, and lack style.
Really don't like tats on women....have seen the odd dragon on martial arts men that I found quite sexy! When taken to the extreme of "hinges inside elbows", "spiders webs on outside of elbows", and "mother on upper arms"; tis not a good look....and having seen a plethora of Navy tats in many unmentionable places...it just leaves me cold. (The boys like to brag!) Guess tis like anything...horses for courses, within time and place context.
However, one of the best secretaries I ever had, had 5 holes in each ear, plus ankle and wrist tats. She was very efficient with great customer service. Couldn't fault her. Mind you...some of the customers did look twice and a couple of them couldn't hide their sneers!
