I knoooow. Like breaking into the morgue and taking pictures of dead people so you can be like "So sorry, can't make it tonight. My Granny died. Look, here's her corpse. Just in case you don't believe me".
I work in a hospital so take sly pictures of ED signage or people's hands with canulas in (the waiting time board is a good one too). And say 'sigh, guys I've had to go to ED again. Have fun. Don't worry, I'll let you know how I got on in 3 days'.
Genuinely though, this happened like a week ago on our staff night out. And I think it's just the hassle of getting there and stuff. If I had a teleporter, I'd probably still not go though.
