Did you get special service? for me If don't have nothing done, fair and sq.
Had a similar experience. Walked into a Mercedes showroom looking for the service centre dressed in jeans and t shirt and sweating like a pig. Was totally ignored until one sweet middle aged lady came up and asked if she could help. She pointed me in the right direction and then asked me to come back and look at the new merc on display. This I did. A month later I traded in the old merc for the new one with her.
