'China Buffet'
'salad bar'
a neon martini glass


When any of the above are part of the signage... move along. Nothing to see here.

I'm sure there's PLENTY more. My uncle used to have what he called 'iron-clad' rules about where not to eat. Included but limited to:
If there's a salad bar
If they announce your anme over a speaker when your table is ready
If you are handed a vibrator when giving your name for a table
