I don't recall wishing you a Happy anything...

Which is why I am not a person who says merry christmas, happy holidays to anybody.

[Primer]

As a teacher, I just say, "Have a good break."

Io Saturnalia!

Awesome! We used to celebrate this every year when I was in high school! Man, I mis my latin class. (hey! I'm not that big of a nerd! )

So have a Merry Christmas, a Happy Hannukah, a Kwazy Kwanzaa, and a Solemn, Dignified Rahmadan.

Salesmonkey, you forgot a Tip-Top Tet. Hehe.

A few years ago I worked at a restaurant as a hostess. Around the holidays, my fellow hostess wished a man "Happy Holidays" as she held open the door for him. He looked at her and said emphatically "You mean Merry Christmas. Don't be so politically correct."

She replied cheerfully, "Well, sir, I'm Jewish, so if we are going to get specific, Happy Hanukkah."

He turned a few shades of lovely red and muttered "Well, yes, happy holidays then," and left.

And commence with the laughing.

There's no corporate policy in place at my store, so I'm left to wish people whatever I like.

My default phrase is "Happy Holidays," however...

If they are wearing Christmas-themed anything, or something that indicates they are Christian, they get a "Merry Christmas."

If they are wearing, say, a Star of David pendant or necklace, I wish them a "Happy Hanukkah."

If they are clearly neither Christian nor Jewish, they get a "Happy Holidays" and I never get an objection.

If they object and say, "Merry Christmas," in that tone that says How dare you take God out of Christmas, I will happily return the greeting, and they relax.

...and if they're wearing a pentagram?

Perhaps "Happy, er, Solstice?" would work.

I struggle with this at work because they are after us to pester anyone calling in to buy flowers to place a Christmas order at the same time. I don't feel comfortable doing that because sometimes I'm taking an order from someone that I know by hearing their accent/last name/location it's not likely they celebrate Christmas and they might be offended if I mention it. So.. I try to just mention ordering for 'the upcoming holiday season' figuring that encompasses Hanukkah, Kwanzaa and Festivus For The Restofus.
