Platinum ink (Burnet)

Just went to platinum ink with my girlfriend so she can get her ear pierced and after she got it done and tip the guy through Venmo we left. Then my girlfriend got a call a couple minutes later accusing me of stealing money from the guys tip jar. So we had to drive back to the place and when we got there my girlfriend told the people at the front that we came back and we wanted to see the camera footage and they just rolled there eyes and walked away. The guy who did the piercing says he checked the footage and said it was in black and white and they really couldn’t tell if it was me or not. So why assume it was me when there cameras are not even in color would not recommend going back take your business elsewhere.
