Places that I have noticed and I appreciate them saying Merry Christmas!
The Martin County Building Dept.
El Toros (Feliz Navidad)
Fugu Tie (Thanks for Annekas Zu zu pet and "Gun Tso Sun Tan'Gung Haw Sun")
Plaza Paints (PSL)
They don't have to say it, they are not required to say it - but it's nice that they do. The whole world hasn't gone to hell in a hand basket yet.
