How much is customary to tip the tattoo artist?
A good rule of thumb, is tip as you would for your beautician, massage technician, nail artist, or a good meal. 20% means you love the work and were very pleased with the service you received while in the tattoo shop. 15% means the service was good. 10% means it was OK. 5% means you probably should not tip. And, 0% means you probably will not be coming back to that shop. This is only a rule of thumb. And, it is ok to tip the owner as well as the piercer.
