I'm with you on it all except for the DQ thing. There's two bits to that. One is that they kinda force you to do it. The renaming the cups into something they obviously know what you mean? Yeah that's just annoying and no one cares. But if you don't flip it you can get it in shit. Part of that is also due to number 2. Flipping it isn't just a marketing trick, actually checks the ice-cream and stuff as well. If its freshly made and it flips but slides out then the machine isn't setting the icecream to the right temperature and that can indicate other issues.

Like it's ABSOLUTELY a marketing trick but it's one that is forced on the employees. However at least this marketing trick has an actual secondary purpose instead of just being frilly bullshit for literally no reason.
