Furniture delivery isn't as dangerous as fighting crime and fire of course. But there are good economic reasons for taking sales people for a ride on a delivery truck. And nobody is ever happy about them. Customers are disappointed. After all, they bought and want the furniture.
Crews are unhappy.
They strained their backs trying to shoehorn in a piece that simply couldn't make it. That could lead to damages as well as time loss. Sales people are distressed-especially if they work on commissions. And, of course, all this wasted time and effort costs you dearly. But they're sure to start asking questions to make certain every piece sold can be delivered and stays sold.
