My prius car suddenly stall during driving. so I towed my car to this store as towing company said it is closest mechanic. It is the first time I visit it.

I dropped the car at parking, the front desk told me I had to wait for 30-60 minutes before they can check,as every body is busy. I thought I could seek a second opinion during waiting since one mechanic told me over the phone there might be some complicated circuit problems. so I went to another store right next to do it for checkup. after 30 minutes I came back asking for this guy's diagnostic checking up. one old guy came in and yelled at me: questioning me why I went to his neighbor store. I had no clue why he is so rude and mad at me. I understand he hate his competitor. But I am the customer,I had every right to seek various opinions before I make a decision.

The old guy told me he was the store owner and major engineer. apparently he is senseless and still need to learn how to treat his customer from ABC. I will be very surprised he know how to repair a relatively complicated car problem, as he even can't figure out the simplest mechanism related with his customer.

I will let all friends around me how bad this store is
