How can more stops be added when the truck has already left the warehouse with only what was supposed to be delivered on the route he has. Do you think companies send drivers with extra inventory in hopes that someone will place another order???? You are totally missing the point. There is absolutely no way to get more product onto a truck once said truck has left the warehouse to complete its route unless it’s coming back to home base to reload. There are thousands of businesses that don’t rely on huge trucks to get to them. It’s sad that you don’t realize that atleast 50% of orders placed by businesses don’t require trucks or vans. It’s the little guys with their personal cars doing the running around.
