I check in and review. I'm a yelp fan, but I'm not a business owner. Most bad reviews on tattoo shops are from people who don't understand them. They expect the people in the shop to fall over themselves to help them. I look for the 1 star reviews for the laughter it creates.
Here's one for Saved "Their work? Absolutely gorgeous. Their artists? Absolutely top notch, I'm sure. But that's as far as I got. Their customer service? Notsomuch."
So her ass wasn't kissed and she didn't like that. But she did like the work.
EVERY bad review for a shop reads this way. I haven't read a bad review yet that sites crappy work.
