I tip the van driver $2, and more if it is longer limo ride. I also tip for my FO if he is on first year. But WTF, why is it my responsibility to compensate all the people on crappy pay. Would it not be better if everyone made a living wage and nice people didn't have to compensate for all the cheap asses out there? BTW with this logic I should go through the cabin for tips because I am the lowest paid pilot out there...
