AITAH for not helping my manager with a simple request?

I work for a package delivery company, and one of the things we’ll do to help each other is give a package or two to another driver for them to code it a 12, which basically means it was put on the wrong truck. We don’t do it often, but will when it’s a busy day and the driver couldn’t find the package when they were in the area or it was in the wrong spot in their truck. Just saves them the trouble of having to go back, and doesn’t penalize the driver or the company.

Today my manager wanted me to 12 a package for him, and when I told him I wasn’t trying to do that I can tell he was pissed by his response. The reasons I said no is anytime he works on a Sunday (once every 3-4 weeks) he wants me to 12 a package, or help with his route because someone called out, etc. I usually always say yes, but with grabbing the package from him he doesn’t ask he tells me to come get it, and I have to chase him down which adds 30 min to my day. On top of that I’m working 6 days at both jobs and I just wanna go home and not do extra shit.

The thing is I’m friends with him, and he’s a good manager so after I felt like it wasn’t that serious for me to make it a thing. So I’m curious AITAH?
