If you chose to live in a pigsty at home, that's fine. In the office, however, everyone has to be considerate of others. There are 100 people on our floor and clients sometimes walk through the kitchen to get to the toilets.
I specifically said what to do if the bin is full and yet I've just been in the kitchen to find it overflowing and 4 empty boxes/bags on the floor and others on the surface. Use your intelligence and all make an effort!
This has gone to the entire company. I wonder if she will have a job tomorrow.
