Scratches is nothing, let me share my story here.
Sent in my car for 10K service with $88 added for car wax.
When the service exec took over my car, he drove my car and bang on the wall right in front of me.

then he came out and complaint my brake lock is blocking him and he cannot stop on time.
I was thinking how the heck he can shift the gear if he didn't manage to step on the brake.
Fine, then "out of good will", they will fix everything nicely for me.
At the same day, they call me up to collect my car and still got face to collect $88 for the car wax.
On the bright side, at least I did not notice anything on the damage area. What a service...
I think, will most likely send my car for 20K service outside. I don't want to pay for this kind of service.
