About a decade ago, I used to work doing customer service for a power company in Texas. As you can imagine, a great number of my calls involved late bills and disconnections. And it's not like the company was ruthless - due to Texas regulations and the general PITA of disconnecting/reconnecting someone, it generally required being 3+ months overdue to actually get shut off. So it was hard for me to work up much sympathy for anyone who was disconnected for delinquency.
But the absolute best was the guy who called up screaming at me about his power being off, because he'd just bought a whole load of rare exotic saltwater fish who have to be kept temperature-controlled. And (of course) he was totally unwilling to pay anything towards his bill either, because he'd spent his money on the fish.
So yes, I DID say exactly what any reasonable person would be thinking at that point, "Well, then you should have paid your electric bill BEFORE buying fish that require you have electricity!"
(I was the rep customers got escalated to when they were assholes who refused to pay, and I had a lot of leeway to be almost-but-not-quite rude to them in cases like this.)
I told him WHEN he paid his bill, he would get electricity back. Not before. I feel bad for the fishes tho.
