Do people living in buildings without elevators order drinks from Coupang?

I live on the 2nd floor of a studio apartment without an elevator, and I frequently order 12-packs of 1.5L Zero Coke (since I drink Zero Coke instead of water). I heard the delivery while I was home, and the person seemed to be making somewhat huffing(?) or dissatisfied noises while thumping the drinks down.
I do realize it must be close to heavy manual labor, but..
Would it be better if I didn't order drinks?
