There was this client who was allergic to a certain type of ink, but didn't know it. The tattoo artist didn't do a proper patch test either. When the tattoo was being done, the client's skin started to have a really bad reaction. It became red, swollen, and itchy. The client was in pain and distress. The artist felt really bad, but the damage was already done. It led to a lot of medical expenses for the client to treat the reaction and a lot of bad feelings between the two.
A client booked an appointment for a large and complex tattoo. The tattoo artist underestimated the time it would take. Halfway through the session, the artist realized they couldn't finish it in one go as they had other appointments scheduled. So, they rushed the rest of the tattoo. The result was a sloppy and unfinished - looking design. The client was extremely disappointed and angry. They demanded a refund, but the artist was reluctant as they had already put in a lot of work. This led to a long and bitter dispute.
Sure. A client had a very specific design in mind. They showed the tattoo artist a picture of what they wanted. But the artist completely misinterpreted it. Instead of a beautiful, detailed flower, the artist ended up creating something that looked like a child's scribble. The client was horrified and there was a huge argument about what could be done to fix it. Eventually, the artist had to offer a discount on a cover - up tattoo, but the client was still very unhappy with the whole experience.
