I was deep in discussion today with 3 of my bosses. I was standing in a doorway. Another staff member came up behind me and stuck her fingers in my ears.
I whipped round shouting "Jesus DON'T do that to me! You didn't know if I was going to turn round a punch you!".
I'm not close to this person but actually had no clue who it was- just an instinctive reaction. I mean who the hell actually DOES something like that in a work environment? We are actually a registered profession too which makes it even more bizarre behaviour.
I'm still cross about it now!
