So as trivial as this may seem, the debate rages on over whether or not to say "Merry Christmas" or "Happy Holidays" to people who you do not even know.
Isn't it simple to find the answer?
If you don't know someone, why assume they are Christian?
What's offensive or less meaningful about saying "Happy Holidays?"
What is the built-in or inherent superiority in saying "Merry Christmas" ?
Working at a store in a strip mall I see this little battle raging everyday.
I TRY to avoid the issue all together by saying, "Have a nice day," or "Have a good night," maybe "Have a great weekend!"
Other employees at the store sometimes do say "Happy Holidays," which is fine, if you are willing to deal with the more than occasional proclamation-esque response of "Merry Christmas!" Which normally might not pass through your ears causing any stir of emotion, but these people say it like they are proving a point.
Then they follow it up with a look in their eyes as if to say, "Yah, that's right I SAID IT!"
I even get this holier-than-thou, that's right I DARE to assume you are Christian - Because I am one and I'm a rebel who is doing something NOBLE!!! - Response after saying "have a good day!"
What's the deal with people?
