It should be possible to pay for something while still having “best effort under shared resources” as the expected service level. Compare local bus tickets vs taking a cab. The taxi costs 20x more, but in the best case scenario, they provide exactly the same value! If the bus is late, cold or overcrowded, I have no expectations to get refunded or even an apology. I just have to suck it up. This happens rarely enough that I still accept it and hand over my trust to them. There is no illusion that my $2 bus ticket alone is enough to keep the bus running, in contrast with the cab. (Bus companies having a tough time to profit is an orthagonal issue, taxi drivers struggle a lot too)
