I faced a moral choice with a customer's worn cassette

A regular customer brought in a bike with a worn cassette and limited funds. Most mechanics would insist on a new one for safety, but I checked the wear and found it still had life. I cleaned and reinstalled it, explaining the risks, and the bike has been fine for months. Sometimes, being too rigid can push people away from proper maintenance.

Someone mistook my CAD printout for a disposable placemat

I left it on the cafeteria table. Came back to find ketchup stains all over the elevation views.

So I was mixing mortar and a cat walked through it. Paw prints all over the fresh bricks. What a mess lol

My kid spotted smiley faces on cereal logos everywhere.

It's a common brand style to seem friendly. Wonder if it really connects with families.

My supervisor keeps taking credit for my install ideas

I suggested a better way to route cables in tight spaces, and now he presents it as his own in meetings. It's getting really old, and I don't know how to call him out without looking petty. What's the best way to handle a boss who steals your tricks?
