Blazze

The big guys keep interfering with lawsuits and disputes over contracts. They’ll probably delay the thing by a decade.

You don’t legally have to stop and show your receipt (except Costco). I have a friend that pont blank tells them “nah” every time. Catch is, security can legally detain you if they really suspect something.
For me it’s not worth the hassle and I just show them with an annoying look.
