My parents were looking to purchase a new car and were having a hard time deciding between A4 Quatrro vs. Volvo S60 AWD. They visited Hoffman Audi last weekend and fell in love with the car and the customer service. They asked for my opinion and wanted me to be present when they pick either one. Today, I visited to check out the A4 that my parents fell in love with. My mother, along with my sister were going to meet me bringing the check book along. Adrian, their sales consultant went above and beyond to answer every question and even decided to come join us on his day off. Prior to visiting him, we made sure our intentions were clear. Both A4 and S60 are amazing cars with similar price range. Since both had pros and cons, we knew we had to compromise one way or the other so we decided that cost is going to be the decision maker.

While we were in middle of negotiations trying to finalise a deal. Adrian was going back and forth between his desk and the managers office behind him. We gave him our last offer which wasn't too far off and was also the price I was quoted for Volvo. Mr. "Manager" comes out of his office with his first words exactly being "Why would you call my guy on his day off if you didn't want to purchase A4" Before I got the chance to explain, I was cutoff with "I am not talking to you, I am talking to your mother." Results included getting up and walking away.

A) You don't talk to any potential customer with rude attitude. Even if you didn't mean it, Apologise right away.
B) Adrian chose to come to work on his day off to finalise the sale, we just called him to give him heads up that I was heading down. It wouldn't have mattered to us if someone else benefited from the sale.
C) YOU DON'T BELITTLE ANYONE WHO IS WILLING TO SPEND MONEY IN YOUR ESTABLISHMENT. Doesn't matter if the guy is going to purchase an A3 or and R8. EVEN IF YOU JUDGE CUSTOMERS YOU CERTAINLY DON'T MAKE THEM FEEL UNCOMFORTABLE OR UNWANTED.

To Adrian,
I apologise, I didn't get a chance to appreciate all the time and effort you put into us. We came in with the right intentions to buy the car from you, it's your manager that cost you this commission. His fantastic people skills made the decision for us to purchase S60 down the road, not the price.
