Watching my favorite stop sign, and stopped a Marten Transport salesman

So, there I was watching a stop sign that people run in this industrial area, and a car runs it. I stop him and tell him the reason he got stopped. I ask him where he is coming from, and he tells me from a cookie plant. I ask him why he was there, and he tells me he is a salesman for Marten Transport.

He tells me that a full reefer load to Chicago pays $1.20 a mile, at which I scoff and say "how are y'all able to get by on those rates?"

I started to tell him that friends of mine in the area haul frozen chicken with just their dot number and no authority for $2.00 plus a mile, but I didn't want them to come in and cut the rates. I should have asked him for an application
