Why metro minimums are lower
A fifty-pallet minimum inside the metro and a hundred and fifty outside it is not a pricing preference; it is diesel arithmetic. Inside the metro the truck is already within twenty minutes of the yard and is probably passing anyway, so a small collection can ride along with a scheduled delivery.
That proximity is also why closed loops work best here: dense customers, short lanes, and enough volume that nearly every outbound delivery can be paired with an inbound collection.
