I hate to be that guy, but all the stories in this thread are fake because the bartenders can just skip the songs. For exactly this reason. As if the people who designed these machines didn't think of this exact thing.
And they all have this? I've seen bartenders go all the way up to the machine and use and pay like a regular customer when I'm sure they would've used the remote if they had it
I don't know about these modern things like shown in the meme, but all the juke boxes in my area when a place has one at all, is old as fuck (most of them still use 45's) and can't skip songs. At least, not without unplugging and resetting the whole machine.
