I have taken our two cars here for two years, with good results, and courteous treatment.. Usually from a nice Asian girl who treated all customers with professionalism and courtesy.. Well, that didn't happen the last time I went, two weeks ago.
There aren't enough parking spaces, so I was in front of the store trying not to park on a red curb.. A mechanic stopped his work to come over to tell me to park next door.. and that he'd "get my paperwork started". But when I went to the service desk and mentioned what a mechanic outside had said, a young man behind the desk got arrogantly huffy with me, and brushed me aside.. He crumpled up my coupon I had given to him, and threw it down, saying he didn't need my business! Needless to say I left. The manager came after me to find out what happened, but by this time I would rathe have had my oil change done by homeless guys in Las Vegas Wash.
Don't go there until they get their internal "rice bowl" problems solved, and learn to remember their salaries are paid by customers.
