Merry Christmas for me and I'm as non religious as they come. It's more so how I was raised and frankly fond family memories. Many of the bigger stores are pretty much told to keep it "Happy holidays" as to not offend or exclude anyone but I make it a point to drop Merry Christmas at every dealing or transaction. If someone tells me Happy Hanukkah or what have you I'm not offended in the least. It's what they know, like and follow so all the power to them.
