These days I am a Grinch. I do not enjoy the Christmas season for reasons I won't bore you with.
HOWEVER
As you go about your own preparations for the season and jostle 50,000 close friends you've never met while hunting the perfect gift or decoration (or even just a burger), remember, those folks working in the stores and restaurants are people also. All they are trying to do is take care of business and go home at the end of the day. And they are having to put up with the same 50,000 assholes you are.
So, give everyone else a break. Say thanks and please and give them a smile. If nothing else, they will wonder what you are up to.
