Oil Change & Tire Rotation

My wife went here to get an oil change, and they offered to rotate our tires. When I get home and check the car, the tire air-pressure warning was on. Earlier that day, the warning light was not on. The PSI prior to that visit was ~33, after that visit it mysteriously dropped to less than 20 PSI! Nice scheme they have there, let the air out so they blow on the highway and we have to buy new ones. Someone could have gotten hurt or died. Don't ever go to this location, staff is inexperienced and sabotaged our tires. They couldn't even figure out how to reset the maintenance timer on our car. If you've gone here recently, be sure to check your car out!
