STOP putting out Facebook pleas for "prayers for my brother who........(tells of medical procedure/personal business)" If he wanted the world to know, he would tell them himself. MYOB
I waitressed all through high school and college---tend to over-tip. I will also say "You guys are hustling here--thank you!" out loud when I hear a snarky customer complain out loud.
if service is slow, but everyone working seems to be hustling their a$$es, I know it's a management or short staff problem. People need to deal with this kindly
