That is totally disgusting! I hope you have contacted the board of health on this matter. Staph infections are very contagious and if not treated quickly can become a nightmare all over your body. These usually scare leaving marks like cigar burns. You absolutely need medical attention and an antibiotic quickly. That employee shold never had been working on you in the first place...you have to wonder how he caught it. Usually this bacteria lives for days and breeds on tools used in salons and in water. You need to write a formal complaint and have this business investigated. I am a salon owner in Toronto-not for tatoos though. An esthetic spa. Good Luck to you- dont let this go. Take pictures of the leisions and send them to the appropriate authorities.

All the Best
