>You walk in and your neighbor is working the cash register. This is a total fantasy. 1. If I was concerned about it, I probably would have noticed before entering that he was there. 2. If I knew him, I'd probably know where he worked and could avoid him. 3. If I didn't catch myself in time, I could walk in and buy something mundane, or nothing at all, or a gift card. 4. If I was really concerned, I'd go the next town over. 5. There's a massive difference between taking a very low probability risk of being identified multiplied by further low probabilities of it being spread notable, remembered, and spread around, and a 100% chance of being categorically identified and logged by an automated system.
