Sounded like the sales guys are in a queue. The next one in the queue gets the next customer to walk thru the front door. If that guy ain't buing a car, too bad. He's your customer. Essentially, sending him to the back of the line.Lose what spot in what line? Do they line up like Taxi's?
Either way, I would have just said I was only waiting for my wife and NO, I would not use another entrance.
He was not rude. He asked politely. I saw no need to make a stink over the dealer policy. All that would end up happening is that he'd be at the back of the line.
