From a Marketing standpoint, when you see a TV commercial like this or the ones where the Car Dealer is screaming and not using good grammar...that denotes the customer base they are seeking and trying to attract. They are speaking to those they believe to be their customers.
In this commercial the trailers he shows are wrecks and so he is speaking to the good ole boys out there that will probably pay by the week...he said he will cover up the stains...that's all his kind of customer cares about.
The man knows his customers and is going after them...
