Southern Accents: A lot of truckers are from down south, so I have been exposed to a variety of southern accents.
I think it's in Tennessee where they sometimes trail off the end of the sentence, as if they don't even have to complete the sentence, which makes my eyeballs almost pop out.
One time in Mississippi I paid a shop bill, spun on my heel to leave, but turned back around when he said "come back". When I turned back, he was already walking away. I later on decided that "come back" was short for "y'all come back now".
Up in Virginia I've been told "I'm fixin tah do it, right quick".
In North Carolina, when buying a can of soda at a truck stop and saying nothing, I was told at the end of the transaction, "Come back and see us again".
One time I was discussing armadillos with a colorful Texas lady cashier, who told me, "armadillos aren't cute. They're varments! They dig up the foundation of the house. If I see one, I get my gun and shoot it."
By the way, the old saying among truckers is "the only thing in Texas is steers and queers". I think the saying came from the past, where there might have been more cruising of truckers at Texas rest stops, as compared to other states.
