I was a Sunday walk in for a nose piercing. I was greeted in what I thought to be a reasonable amount of time... I was given paperwork to fill out, and was waiting for the artist to become available. I was provided with post care instructions that were very clear and concise.
Once I was with the 'piercer' he was very personable, and asked if I had any questions, marked my nose, and went for it.
Although I have wanted a nose piercing for years, I hadn't done much research... blow your nose millions of times prior to going in.... be prepared for a betadine cotton swab to be shoved up and wiggled around your nose. The piercing didn't hurt too badly, but threading of the ring wasn't too pleasant.
You are provided a bottle of betadine to clean your ring.
Over all, I am happy :-)
If you're looking for a tattoo, make an appointment, esp for a Sunday.
