You tip because you're out for coffee while they're at work, and because $7 is almost an hour of someone's life at minimum wage. It's called noblesse oblige, and it's what rich people used to do instead of subsidizing libertarian websites.
These people are dogs and believing that you’re capable of engaging w them in some kind of dialogue belies a childlike naïveté. Your time would be better spent trying to train a pitbull to use the toilet.
I’m very concerned that political leaders are aware that something is happening or about to happen that dwarfs even the horrors we’ve seen every day. This is just speculation on my part to be clear, but the warnings about a mass starvation tipping point have been growing louder.
