I don’t like them. They tend to be inaccurate for anything that contains information, such as might benefit from reading more than once, or pondered over before understanding. And if it’s meaningless, then why would I even care if I get interrupted midway through it?

I think you can get away with just about anything, so long as it doesn’t piss off anyone with a bigger navy than you own.

The least precision expressed on my monthly utility bills is 1000 gallons. Usually I either get rounded down to 0 or up to 1000 Gal. Check your bill again and find out what sort of units apply to 13 and 24 – it isn’t gallons/month.

Yes. I didn’t like it.
