Landlord comes and cuts the grass whenever.
Came to replace a smashed window another day after a stone flew from the mower the previous time he cut it.
Doesn't bother me.
Actually, one time we had a minor leak and he was to come around to fix it but didn't say a specific day or time just "some day". My housmate was off work that day and is a big strong bodybuilder guy and not a type to take any crap. He was in his room. As landlord was coming in the hallway my housemate was coming out of the room onto the landing. They both stopped stunned and stared at eachother up/down the stairs for a moment. The landlord wasn't expecting anyone to be home. Housemate didn't recognise landlord as he had never met him in person. His first thought was that it was a burglar coming in as landlord was wearing rubber gloves, ready to deal with the leak. Housemate moved to the stairs ready to confront or beat the landlord until the landlord panicked and pleaded with him "oh no, no! It's ok, I'm the landlord, I'm the landlord, its OK"
This all happened within a space of 3 or 4 seconds.
So yeah, there can be misunderstandings....
