On a Friday I call into a supermarket local to my work and pick up lunch (for myself and others).
Today there was a queue to use the coffee machine and I ended up being 3 minutes late for work.
When I got into work I apologised for being late and my line manager said to not let it happen again and to make up the time in my lunch.
I did my 3 minutes of work and then went to take my lunch in another room.
At my finishing time I got up and left and a member of the team mentioned something about swanning in late and leaving early to which I replied I'd made my time up as I'd been told to by our manager and I didn't realise that they were now my supervisor.
He followed me to my car to try and start an argument but I kept walking got in my car and left.
He's known in the workplace to be hotheaded and very argumentative and management have had to step in/give warnings before now.
He's tried to call me twice on my personal number but not left any messages.
AIBU to ignore until Monday
