Man, that's the classic hidden gremlin right there. Did you happen to check the gasket with a dollar bill test or just spot the warp by eye? I swear those bottom corners are the first spot to go bad on any fridge, especially if it's been bumped or dragged.

never approved in writing" hits hard because I've totally been there. One time my cousin spent like three days building a whole website for a guy who kept saying "yeah that looks great" over the phone. Then the guy saw it in person and said he wanted a completely different color scheme and layout, like from scratch. Turns out his business partner was the one who actually made decisions and he never even saw the first version. My cousin didn't even get paid for the first site, he just ate the hours because he felt bad. Now he makes everyone sign a one page agreement before he even opens Photoshop, no exceptions. It's crazy how a quick email saying "we approve this" can save you a whole weekend of misery.
