Fair enough. I have another anecdote about this. Another friend went into a Ford dealer to buy a truck with all cash. The salesmen just ignored him, chatting around the coffee machine. He came up to them, and pulled out the roll of cash, saying he came there to buy a truck and "I'm going to the other Ford dealer." The salesmen rushed him, but he said "too late".

He walked out, went to the other Ford dealer, and drove out with a new truck.

I can see not wasting time if there are many customers in the place, of course you triage them. But if you're chatting around the coffee machine because there are no customers in the showroom ... !
