It should depends on service. When I came back last week, the cab driver didn't help me to load or unload luggage. There is one car seat in back trunk, so I have to put one piece of my luggage on the back seat. But still, I give him like 20% tip. I really don't know why I did that. My execuse is that it was really late(around mid-night).
