Someone posted this question on social media:  “At a restaurant, what’s something that’s an automatic, ‘I am NOT eating here, we need to leave.’  And here are the best responses:     1.  Blaringly loud music and strange lighting.   2.  No soap in the bathroom . . . and no hint that it just ran out.   3.  The smell of a dirty grease trap.  If you’ve worked in a kitchen for a while you recognize it instantly.   4.  Any bad smell.   5.  The cook walks out of the bathroom . . . with an apron on.   6.  A massive menu that’s all over the place, even the Cheesecake Factory.   7.  No prices on the menu.  Or no menus at all, just a QR code.   8.  Lots of flies buzzing around the tables and the kitchen.  Or worse, the sight of even ONE cockroach.   9.  Dirty floors . . . filthy bathrooms . . . or sticky tables.   10.  Poor hygiene from the workers, including being visibly sick.   11.  When the workers see you come in . . . and look annoyed that they have to work.  Or sitting down and being ignored for 10 or 15 minutes.   12.  Any restaurant that posts semi-permanent excuses on the front door, like “We’re understaffed” or “No one wants to work anymore.”  It shows the place can’t run a business, or doesn’t treat employees well enough to stick around.   13.  There are TVs playing the news . . . especially anything politics related.   14.  There are children screaming or running around.   15.  Gordon Ramsay is filming inside.     (Ask Reddit)
