Ditmars Auto Repr

As a gas station, this place is pretty good. It’s completely full service for, and there’s usually no lines. The auto repair shop, however, leaves something to be desired.
An oil change is $ 40. There are plenty of places on 21^st Street or Northern Blvd for $ 20-​$ 25. Plus, typically when you get an oil change they check/​top off your other fluids, and do a general review of your car (brakes, etc.).
I dropped my car off this week and when I picked it up they didn’t say anything. No notes, no feedback, no nothing. I happen to know that two tires are worn down and I figured I might need new brakes but I wouldn’t know it from this place.
When I tried to pay with a credit card, the guy got annoyed with me and said that I was keeping him from his customers. What do you think I am, crazy muttering guy? A customer — that’s why I’m paying you!
