What other ways do you think society was changed by the invention of the telephone?

"Ridiculously annoying companies can phone you up at ridiculous hours of the morning and offer you PPI or a new network or phone provider or something else you're not interested in. But it made it easier for society to just ignore salespeople because it's easier to put the phone down on someone than it is to slam a door in their face. You feel less rude."

And he should know, he'd done both of those things many a time. Dalton was sure that secretly, everyone he lived with was bloody overjoyed when it was him who answered the door or the phone - communication with the other party seemingly ended fairly quickly when that was the case. Unlike a lot of people, he didn't have a problem with being rude, just an opinion that they should have chosen different jobs if they didn't like his reaction.

What even was PPI?

Something NO one cared about, he was sure.
