Shortest route is not the most monetarily efficient. If they need to deconstruct a pallet, itll go to where it best fits before it gets distributed to other routes.Not to say usps is the best at this, but a common logistics scenario.

I used to work for a company/industry/product that was extremely temperature sensitive. To the point that reefers (refrigerated cargo units) could only maintain temps +/- 5 degrees before spoilage. Those crazy routes were pretty typical based simply on the weather.
