My favorite way out of that situation was to tell them that the registers were automatically shut down at closing. Literally no way to ring up a purchase. It worked most of the time
“Can’t you just do it on paper?”
“oh that’s okay, I have cash, coin, and check”
“Can’t you fuck off?”
Sure, just let me buy this one thing first.
Ok, I’ll ring you up tomorrow, just wait right here.

That’s why there’s the JADE acronym. You never justify, argue, defend, or explain. That makes them think there’s a chance if they just counter every single thing you say.
I usually lead with, “That’s out of my control,” or “that’s above my pay grade.” Most of the time people get it.
My go-to was the ovens have already entered shutdown mode and cannot be restarted. There was no such thing of course.
