Yes, today I got yelled at by a customer because I wished her "Happy Holidays." She sneered, "It's 'Merry Christmas'!"
I said that I was, first off, an Episcopalian Priest, and that I have friends who are Jewish, Muslim, and Wiccan. Since I want to wish all my friends the best of the season, I tend to go with "Happy Holidays."
She started to say something about Holidays and "Holy Days" and some other thing that made no sense.
So I just wished everyone a "good day" from then on.
The love of Christ in action!
