After a year and a half of regular play at the local joint I was asked for ID when cashing out. Seems like I found their policy limit by accident, I thought it was a little higher. No indication I was targeted, but when I refused it escalated quickly. After a 2-3 minute standoff, a brief period of refusing to give my chips back, and a lot of tapping around on the computer I was paid. How much damage could be done by that? Opinions on how to handle it from here? I will obviously reduce my cash outs, that was just a mistake to let that happen. Do I need to take other precautions?
