pardon if i'm being weird or whatever here, but have you tried being proactive about it, telling them that you are not adding any more tattoos, this was something you did when you were younger, and show them documentation that you don't have hepatitis from the ones you already have? This stuff might be a consideration in bartending jobs, where you have to get dept of health tests. It might not be stuff they can legally ask you, but it doesn't mean you can't tell them, and it doesn't mean they can't reject you if they suspect it - as long as they don't ask you, they're legally in the clear.
