My colleague has a private meeting at 5pm and every week for the last few weeks she asks me at around 4:30 whether I'll still be in the office at 5pm and every week I say sorry, but my bus is at quarter past, and I don't want to wait in the cold, so I'll be here for a little while after 5.
It didn't bother me the first week, but it's really getting on my nerves now.
Didn't help that she took a personal call at 4:40 which mostly consisted of her saying 'I can't talk now' while walking in and out of the office.
