Pop your hood and take a picture of the engine bay before and after a service; do not leave the service center until those pictures match. On my wife's initial 5K oil change on her 2016.5 CX-5, the engine air filter was dropped into the bottom of the engine bay while the air filter box was clipped back into place. When my wife complained that the car did not sound right the following day, their service rep told her over the phone they would charge her $100 just to look, and that another dealership would charge her more. I can't say for sure whether this was an attempt to drum up some business, but it did feel like they were getting a bit greedy since I ended up purchasing a CX-3 during the oil change. I came in the next day -using a vacation day from work- the service manager had his techs in front of the dealership in a meeting. He apologized profusely and stated that from now on, a dedicated Quality Control technician would be checking before and after the service. They remedied the problem at no charge, I just had to complain about it myself using a vacation day to do so. He seemed sincere and he'll have 3 years to prove it on two different Mazdas. Until then, I can't recommend this dealership for service until I see that it wasn't just lip service. These may be the last two vehicles I purchase from them too; Finance guys were pretty helpful though. In the picture, that filter below the SKYACTIV emblem does not belong there. It belongs in a slotted box with two retention clips that you can pop open with your fingers as seen in the second picture.
