I had to smile when I saw your post.
Rarely does anyone report to Griffin, Biometrica or even send out a SIN flyer for bets under $200 max. Even at purple/yellow chip max bets many do not send it in. Griffin is a joke and most casinos in NV don't take it seriously. Some little ****-hole in the middle of nowhere may freak out, but not in LV. I've never heard of the EC sending in a pic to any database service on a smaller bets. Maybe if you were playing the table max.
If you are part of a team or doing something that looks like cheating, that's different. Casinos HATE teams and cheats. I wouldn't worry about it. If they were really pissed at you, you'd have been barred from playing or 86'd. Flat betting is not bad. You can probably play on another shift.
