There's always gonna be some jackass that gets offended by anything someone says.
For example:
"Good Morning"
"What's so good about it?"
Example 2
"Merry Christmas!"
"I'm Jewish"
So really there's no point in trying to make everyone happy, because in the long run you're only gonna make yourself miserable trying to figure out what everyone else's problem is.
This piece of sociological advice brought to you by the good folks at the
American Sociological Association where, "We may not actually BE better than you, but we'll sure make it sound like we are."
