Whatever a company gets for doing AAA shit has nothing to do with the people who do the job. You took the job, knowing what it pays, and that's that. A tip isn't something anyone should get, outside of crazy cool service, but now certain industries expect it.
On the flipside, the last tow truck driver I dealt with did back wifemodes car in the garage, and it was Thanksgiving, so I didn't feel bad about tipping him. On a regular day, with a regular service, the best guy in the world can get fucked with the simple "thanks" I extend.
People bring you a simple pizza, walk you over a drink, and fucken demand a tip. Fucken tow drivers want a tip, and I've been painting peoples' biggest investment for years. Whether I hate you, or treat you like a king, it's super mad rare (every 2 years?) that I get a tip, and I'm surprised when they do. Just saying, our tipping priorities are all fucked anyway.
