Logic or Impression

If I like someone and they manage to create a good impression on me I become more comfortable dealing with them. On the contrary I always thought that I am a person of logic and I think logically do things or get comfortable with people.. Maybe not.. I cranked up my car to get to office and must have woken up on the left side of the bed, i guess (Proved to be a bad day for me). The engine check light on my car started showing up on the dashboard. I had this car just for 3 months and I loved the car and did not expect it to ditch me this soon, well my obsession of my car is not what I started to write about.. I had to get this fixed and usually takes a couple of hundred dollars to just get the problem diagnosed, forget about how much it would cost to fix the problem. I called up Audi dealership to check if they can get this taken care for me over the weekend, unfortunately they do not open on the weekends and I had to leave it a the local firestone. The Firestone guys could not diagnose the problem and they gave up saying that only Audi service center can diagnose the issue. I did not have a choice I had to take it to the dealership.
I tried calling up the dealership service guy who had worked on my car before, but could not reach him. I decided to drive my car to the dealership and get it checked. I parked my car and entered the dealership and wandered around trying to figure out whom should I talk to, checked with the immediate counter from where the lady directed me to the service desk. I stood there waiting for someone to ask me what my issue was, while I was waiting I heard this service guy bitching about a customer and complaining about not meeting his yearly targets.
He was talking with his colleague that the customer did not even want to change his worn out tires, I even suggested him cheaper tires if he did not have the money was his point. With these types of customers how will he meet his targets was his concern.
After that I was next to get honored, he checked with me what the problem was and I told him about the engine check light, he told me that they will need at least a day to diagnose the problem. He wanted me to leave the car with them and check back tomorrow. I was not prepared to leave the car, I told him I cannot leave my car on a weekday as I needed the car to get to office everyday.
He offered to arrange for a rental (that was a good idea), for some reason I not convinced and told him I will get the car tomorrow and made an appointment.
I never looked back, not sure why I did that, in spite of the fact that I could not get my car fixed outside.. I still had the engine check light problem. Google once again to my rescue, I looked up for a service center near my office and found one. I called this new service guy and he was very friendly and told me he can fix it, just get me the car, we will fix it for you. He was not an authorized Audi dealer, but for some reason I could trust him and took the car to him next day. After taking a look at the car he asked me if I wanted to change the timing belt on the car, I knew that it was due after 20k miles and I did not want to get it done, he showed me Audi recommendation and told me it is better to change it after 75k miles, sooner the better. I guess I fell for it and asked him to get it done for me. Now when I look back and see what I did, I actually fell for someone who was friendly and did not go with Audi dealership which was not logical, and I ended up spending $1000 more on a job which was not necessary at that time. I guess I still have a lot of thinking on what drives me and why.........................
