Dammit, it's not luck at all.

I'll tell you a way that drivers screw themselves all the time, though.

They'll stand around the dispatching manager and try to hustle three or four orders when it's obvious that they should really only be taking one or two.

They only get a tip out of the first and second orders, and the third and fourth orders are too late and too cold to get a good tip.

Another way they screw themselves is showing up for work looking like every father's worst nightmare.

If you show up at the door looking and acting like somebody I'm not going to let my daughter (or son) go out with, you're not going to get a good tip!

LOL....

If you want to make good tips, you have to lose a little of that self expression.
