Never said it isn't. Big and small. The amount of shit I've experienced myself, or had reported to me by friends and acquaintances is so large that I have a very low starting opinion on small businesses on things not strongly enforced by law. I've shared some more egregious examples on HN a few times, like a practice in grocery stores to wash stale meat with dish cleaner to be able to sell it as fresh. Yes, fraud is very much rampant across business.
