Do you spend your evenings sitting in the kitchen, counting how long it takes to fill a bucket of water from your cold tap, then sending angry emails to your water supplier when it’s not filling as fast as Simon’s identical bucket is three doors down on the same street?
Probably not. That would be weird, wouldn’t it?
It still works. You still get water out of it. There are no obvious bits of poo or dead insects in it, and the toilet flushes. In fact all of the toilets flush even at the same time (you checked), so all’s good, right?
