Bit of a weird one. My housemates are going on holiday for a week and they over heard me telling my mate I'm going to put £20 on the meter and have the heating/fire on as much as I like (I'm freezing).
One of my housemates said it's selfish for me to wait until they're away to pay for the heating.
Basically, they never put the heating on because they don't want to pay to put gas in the meter. But if I put money in the meter they'll use it even when I'm not there, as a result I stopped doing it.
Aibu to put money in the meter and have the heating on as much as I want when they're away to treat myself?
