Ive got a good amount of tats (multiple tats on right arm, cultural tribal from my left wrist to the back of my left ear).
I run my own operation and IMO, there is nothing wrong with tats as long as they can be covered up in a professional environment. I don't think its a good idea to get tats on your hands, face, or neck. If you were part of a professional sales meeting, deals are made based off of your product, likability, and trust. There are a lot of older corporate heads who will judge you by the first impression of your looks (sucks ass...but it is, what it is). Hand tats stand out even more when your wearing a button up shirt to cover up your full sleeve tattoos.
There are a lot of professionals who have tattoos (doctors, lawyers, etc..). You just have to have common sense when it comes to being professional.
