Yea a Gas Bill makes zero fucking sense. I dont pay my gas for 6 months at a time. Not for lack of funds, but out of lack of giving af. The late fees are legit like 25 cents, the bills themselves never over 20. I'll pay it when I pay it, and the Gas Co has NEVER bothered me to do so promptly.
I have to pay my bills, literally, the moment I receive them. Take care of shit as soon as it comes up so ya don't have to think about it or have to remember shit.
