I absolutely hated working retail. You had to be so PC and some people griped at you for NOT saying "Merry Christmas" instead of "Happy Holidays". I am not a particularly religious person but it has been and always will be "Merry Christmas" to me. I think the whole PC movement has gotten a bit out of hand. If you are Atheist, say "Happy Holidays". If you are Christian, say "Merry Christmas". I think everyone should just chill and smile that someone said something nice to them no matter what denomination, if any, they are from.
