It is by far the most important factor when it comes to doing/getting a tattoo that both party's have the ultimate patience. When getting tattooed bring drinks, snacks and lunch to keep your sugar and energy levels topped up through out the day. Bringing in headphones to listen to music is a great way to stay distracted and stops you from talking to the artist and distracting him from concentrating. A phone/tablet to watch movies is also a great idea if your in for a long day.
