Fake thermostat
The weather changes, there are even cliched phrases in every society that reflect this. So, it’s important to be able to adjust the temperature of your home to reflect the season. No-one wants to sit in a room that’s colder than the street outside or be sweating away in the summer. This landlord doesn’t seem to have taken these thoughts into consideration with his “fix.”
Instead of repairing a broken thermostat in between lets, he decided that, as long as the new tenants thought they could change the temperature, it would be fine. So a fake thermostat hung on a nail was enough of an effort. How cheeky is this?
