I had received a gift card for a piercing from one of their block parties I attended. I tried multiple time before I got my piercing to give them the payment because I knew I would forget when I left. The guy with the multiple piercings in his face and through the bridge of his nose told me to keep it til the end as he rolled his eyes. So after I was done getting a piercing from I think Taylor I'm walking out and they are both yelling in front of everyone very loud "you need to pay, its $30 " over and over as the dude at the counter is looking smug. I feel as if they were trying to embarrass me because the dude knew I had the gift card so all of that was not needed. I'm very disappointed in the big brain brand. I will not be back.
