I have seen a bag fee posted on a Lott taxi fare charts. I suppose it is to compensate for them hoisting your bags in and out of the trunk.
My pet peeve, which others see as wonderful service, is hotel valets who have your bags halfway to reception before I have paid my driver. Now I have to tip them for something I could do perfectly well myself.
