I maintain an impeccable interior and my exterior is always at least decent. I groom, speak and dress professionally and finally... I don't do shit for free. Tips are rare, the opportunity to cash in on favors is not. You gotta start straight up hustling with the passengers instead of expecting a tip for going out of your way.

Be polite but short and concise and don't engage in arguments at all since then making you their bitch isn't up for discussion, is it? Straight up ignore them if you must. And remember, you tell everyone you make $30/hr, say it with a straight face (lol) and let them do the math of how much your time is worth is they want to borrow some of it.

You'd be amazed how many people are willing to hand out a $10 or a $20 of you just ask.
