Today I witnessed a GROWN WOMAN handing out party invites to half the people in an exercise class. (I had to double check I was in a leisure centre, not a primary school.) It wasn't like they were quietly being distributed to friends, but ostentatiously being given out to those that had made the grade.
The session then started and we had a guest Zumba instructor. The 'party invite' woman and her crew made it quite clear they didn't rate the instructor, decided to ignore her routines, and to instead dance the routines they knew from our regular teacher; you couldn't make it up!!!
What bonkers behaviour have you seen?
