Seriously painful.

C'mon, does it really cause so much pain that a person cannot bear to be wished a "Merry Christmas"? Here's one guy who went totally off the meter, and paid a price...there's a "Merry Christmas" for ya, buddy. Hope he didn't really need to get where he was going all that badly. Some people make being a total asshole a high art form, I guess.

It causes them no pain, none, zero.

It does, however, give them an excellent opportunity to attempt to exert intimidation and control.
