I hate how 'tips' are used for things like Walmart to offer free local delivery when it actually costs 'price + 10%' unless you want to be a horrible person. It would (and should) cost that price anyway if that's what it takes for the driver to get paid even close to reasonably -- just bake it into the price of delivery and don't rely on people's guilt to have it get done. I would love to see a study on the difference in take-home wages between systems which are setup the same but have one with cheaper out-the-door offerings made through lower base wage and expected tip for the worker. I want to say I would expect the 'tip + lower pay' come out ahead of the 'set wage' on average, but I that may be me projecting my own actions onto others.
