Working in food/retail has completely destroyed all holiday spirit for me entirely.
It doesn't matter the holiday. Holidays just mean my job gets harder with no extra compensation. The customers are more hostile and aggressive and it's just an overall shitty time.
I don't love that this happens, but because I was in those trenches for many years I like to make my holiday shopping trips as pleasant as possible for the retail workers. I'll try to take up as much time with them as I can just shooting the shit and helping them relax a little or giving them knowing looks whenever some asshole engages them.
