Took my car to Honda of Pasadena to replace a mirror which they did.

They also claimed to have done a complementary change oil and filter then have done an inspection. However 2 days after my car was serviced my car alerted me that my oil had hit 15% So they claimed to have done something that they didn't do and as a result I almost skipped my routine maintenance.
