We definitely enjoy eating here. What we DO NOT enjoy is being called "guys." My wife and I are both well-beyond 60, and DO NOT enjoy that level of casualness from anyone. The dark-haired waitress, dressed mostly in black, kept asking "are you guys" this and "are you guys" that. If I had a dollar for every time that she did I could have paid for dinner.
"YOU" is both a singular AND plural word. "You all" would be OK; ditto "you folks." But 86 "you guys" --or worse, "youse guys." --JDH
