My landlord once didn't call the repairman when the air conditioning went out on a Saturday when it was 110°F outside (and remained that way all weekend). She made the excuse that her AC repairman was at a tournament and didn't have anyone come over til the following Monday. You know. When rates were cheaper.
Nevermind the fact that she made >$20,000 in rent from us. She couldn't spend the extra $150 for the weekend rate.
That was the moment I was radicalized against landlords.
