I work as a bar keep a couple of nights a week at a tiny neighborhood Italian restaurant. Last week one of the servers was at my bar inscribing "Merry Christmas" on the top of tickets that she was preparing to deliver to a table. Another server walked by, saw what she was writing, and became incredulous. "You can't write Merry Christmas! You might offend someone! What if they are Jewish? You have to write Happy Holidays." This even though the owner of the restaurant stands at the door greeting all guests with a hearty "Merry Christmas" this time of year. (And the waitress confessed that she had witnessed said table exchanging Christmas cards.)
I said to the two servers, "Let's do a little thought experiment, shall we? If you were to visit a kosher deli and the owner wished you a 'Happy Hanukkah' would you be offended, or even surprised?"
No, they confessed.
"And what kind of restaurant is this?" I asked.
"Italian," they answered.
"And where does the Pope live?"
