Driver only drive lah, not obliged to carry bags. If carry heavy baggage and get injured, who pays his medical fees? If break any items,  he got to pay you?

Your own baggage, you better handle yourself unless you need help. Most will help to carry them together with you if you can't handle it alone.

Drivers drive vehicles
Porters carry bags
Doormen open doors
Chefs cook meals

In Thailand they do it automatically, in Spore people find all excuses not to provide better service. Taxi or Grab drivers should help the passengers to take out big luggage as part of the service, not just a people mover.
