Firstly - I'd love to see photos when this is done!
I'd also like to point out - I have tattoos across my chest and I also have bright pink hair. I've never had issues getting a snr technical position and have never been told that I must cover them at all times.
Lastly, I don't care if you don't like my tattoos. I don't care if you think they look trashy. Chances are I don't like your white lardy ass or long greasy hair. In fact, there's a really good chance that I'm repulsed by it. Interestingly, I don't feel the need to tell you that when I see you in the street.
