I got "saved" at the restaurant where I worked once. Then after I got saved she kissed my forehead and hugged me with tears in her eyes. I was only dropping off their food, it was not even my table.
I thanked her politely and then went in the kitchen and bragged to my coworkers that they were all going to hell but my ass is saved and going to heaven thanks to some lady on the floor.
Never had the whole kitchen crack up like that before. :P
Then there are the times I walk up to a table to check on the food and they're praying.
Now, before anyone gets up in arms, there's absolutely nothing wrong with praying over your restaurant food. But it is uncomfortable when I walk and up and say, "Hey! How's your..." And find I'm interrupting their prayer. "Oh crap. Sorry. Sorry."
Worse is when patrons stop, smile, and ask you to join them in prayer... No thanks I'll just go get some more ranch for that other table and check on you later! It's nice of you to invite me, but I've got at least a hand full of other tables to wait on and if I stop for even a thirty second prayer, someone's going to be pissed that I'm not fetching their juice.
