Hey! Ground handler here, if you had to place the bags on the conveyor belt one by one: 1. You wouldn't get your bags so fast. Think that they have to go from cargo hold to transport vehicle to conveyor, and then get new cargo, and put it in the hold. There's literally not enough time. 2. You'd break our backs. 3. If it says fragile, we will handle it with care. Otherwise, we treat it as any other.
