This is probably the same for anyone who works in retail over Christmas and even though it used to be your favourite holiday (used to be), you now hate it. Work is always busy, you sometimes miss your lunch break and the general public are just nuts and are always stressed out. You now have the Christmas songs on repeat, a Joker smile attached to your face and you're just exhausted. By the time it gets to Christmas Eve you don't even care if you've been naughty or nice, you just want to eat your body weight in baked goods and not look at anyone for around two weeks. But you're working on Boxing Day so you can't even enjoy the bad weather.
