I've got a full sleeve on one arm and two largeish pieces on my other forearm, as well as a half back piece, writing across my collarbones and one on the back of my leg. Never had any problems. I've worked in design artrooms, a bank, a few retail jobs.
If it's the sort of job where you were shirt and tie, they're covered, if it's a job where you wear a t-shirt, it's reasonably likely that they won't mind.
There's jobs in the middle though - where you wear short sleeves but they might worry about them. I went for one job where it was reasonably smart attire but short sleeves, and the interviewer noticed them peeking out and said something, I don't think he liked them much. I didn't get the job, but however a friend of mine got one of the positions and he has tattoos on his forearms, so I don't think me not getting the job was down to my tattoos.
I had an interview recently as well where the interviewer spotted them and asked to see them, so I showed him. I've got a second interview lined up so apparently it didn't fuss him. That was car sales.
So in summary - these days, in my opinion, you're unlikely to have problems if you keep it inside your cuffs. They're certainly becoming more common and more tolerated even by slightly old fashioned people. I think they're just coming around to this being how it is and ignoring it, even if they don't much like it.
Interestingly I never get negative comments from customers, even posh ones. 99% of people say nothing, oiky types like me will often talk to me about them, and a few little old ladies have asked me what I've done to myself. A lady I used to teach always used to tell me off, bless her
No one even mentions the gaping hole in one of my earlobes since I took out my tunnels. I suppose they either don't notice it or don't know what it is so don't say anything. Only one person has ever said anything. She stopped while she was talking to me and leant over, then just said 'what's wrong with your ear?'
