The salesman said he didn't know anything about the TCH because he didn't have any TCHS and he did have XLEs in stock.

It reminds me of the time I sent my wife to Macys Auto Service to get Goodyear tires because they were on sale. When I returned home after work I found Sears(Michelins) on the car. I asked my wife why no Goodyears. She said the salesman told her he'd sell her better tires at the same price. He could have said "Lady, you're in the wrong store!" But then she would have left the store embarassed and he wouldn't have sold a set of tires.
