I'm on-record as a world-class grinch and don't like holidays at all, with the major exception of Halloween. I don't buy presents for anymore, insist that other people don't buy things for me, and try to Solid Snake my way through the festivities, sneaking around undetected until I absolutely must engage.
And as a long-time service industry worker, there's that double-stress of just trying to help out needy people who are trying to seek that 'holiday spirit' at the expense of the sanity of the person on the other side of the cash register. But I get that it means a lot to other people, and they must race out to max out their credit cards on junk that will end up in the attics and closets of their loved ones.
