Tipping seems to be one of these things that everyone hates but tends to do because it's almost like an unwritten code that if we don't, said service may no longer exist in the future.
Now, one of the central pillars of arguing against libertarianism is that if you don't put a gun to someone's head and take their money, that someone will never part with their money unless explicitly paying for a service at time of use. This is somewhat core to the argument that there would be no roads in a libertarian society.
One might argue that you could basically create toll roads for every single road ever, but I think inevitably we might instead opt for a system, similar to tipping your servers, where most people simply pay the area's road construction and maintenance company an annual fee not because we know that we will need to use all the roads but because we know that not paying will eventually mean the roads go away. As we all know, some people don't tip, and some people will not pay the road folks. But we still have waiters and waitresses because most of us understand that, given the current state of our system of laws and environment, servers would go away if we all didn't tip.
I feel like this is a less-discussed aspect of human nature that applies to libertarianism. We see it popping up in progressive areas where museums, for example, will simply have a "suggested donation" instead of a fee, and their revenue hasn't been affected. I wonder if this aspect of humanity should be talked up more in the discussion on why libertarian societies would function quite well.
