Im sure there probably was some sort of class bias that people experienced back before the government got involved in eliminating it. Like before 1963 or something.
Fact is, no salesman keeps his seat very long disrespecting potential customers. Thats why they go through the elaborate qualifying rituals.

When the best are doing it you dont even notice it.

Time is money
No reason to waste either.

People like to buy but not be sold.

Youve probably noticed auto manufacturers all about your buying experience these days. Salesman doesnt play, he dont stay.

Out there doing it best I can.
