To override or not to override.

Recently I got written up over a keyholder mistakenly marking something down way too low. The reason why I got written up was because the customer came back days after keyholder's markdown and demanded I let them by more of the same item for the overly marked down price on a different day and I said "no?" Because it was clearly a mistake. But the customer decided to take it out on me and supposedly called the dm over it.

Today we had the bogo 75% off toys, but only for the leapfrog, vtect, ect. Well whoever closed last night didn't check/pull any signage that wasn't supposed to be there anymore. On top of that for some reason my sm reused paper so one side had the "bogo 75% all toys" and the other had the exclusive leap frog and whatever offer.

I watched the same keyholder argue with a customer because they brought up the sign and still refused to override the prices to make the customer happy because "sm said not to." Even after I said (as asm and specifically because of the write up) we could give them the sale because the sign was still up, and again, to make them happy. But this keyholder was hellbent on "sm said no" and not letting it happen so unfortunately I just let it go.

Idk the whole thing just urks me. Is this key going to get in trouble now? Probably not. But I did. And now I could also get in trouble because I just let it go after they shut my advice down. I even asked the key after the fact "What was the point of me getting in trouble because I didn't make the customer happy before when the sm now told you specifically not to do the same over someone else's mistake?"

Idk if keyholder was just being really petty towards the customer and just saying stuff or not. I also don't really know if the customer who got me written up ever complained about me in the first place, because I told my sm what happened immediately afterwords. For all I know they used my own confession as a reason to write me up. The whole thing is just really dumb.
