One mall here has a food court on a top floor of the mall.
It is circular and has a dozen or more shops selling their
"wares", all varieties of fast food from national or local
chains. The chairs and tables are in the middle of the circle.
My last (believe me: LAST) visit there, I watched a particular
buss person cleaning tables and chairs over a 15 minute period
never once rinsing nor exchanging the towel/rag being used.
Talk about Grubby- pun intended.
