How do I make bars/clubs stay open all night?

You're saying that the bar closes and the bar tender just stays and finishes their shift that we just set? That would make such feature as setting their hours completely and utterly pointless for keeping a bar open. I hope that's not the case, not ready to accept that answer :) .Another possibility is that the feature is for when you put a professional bar on a lot that isn't a late night bar/club. Which I could see it having an actual purpose then. I'm going to test it. I'll report back later when I've had the chance to do so.

Edit: Made my post sound less grouchy. I did just roll out of bed.
