There's currently two issues (although they could be connected).
Please use this thread if your bartender doesn't stay behind the bar but wanders off to socialize, leaving the bar empty. Use this...

Since my post was a duplicate, I'm just reposting my comment and screenshot here. I'm definitely not seeing it as often, but I have had the bartender still come out from behind the bar to socialize with a patron. In the screenshot you can see the bar is left unattended and the bartender is out on the porch talking to a patron. This was NOT at a time when a new bartender was coming in.
Thanks for the screenshot and sorry about the confusion.
