SCs should be flexible enough to allow some level of service for emergency cases. They should at least have a quick diagnosis to ascertain if the car is safe to drive or not. If it is not critical and can't be fixed immediately then an appointment can be made to get it fixed. That was all that TS wanted. He wasn't demanding to jump queue.

For example the check engine light came on for Mazda 3 so immediately I dropped in to a SC without an appointment. The SC accepted my car, checked and cleared the fault and I was on my way in 1.5 hours. I would be very disappointed if I was unable to get any service for my problem without an appointment. How would I know if my car was still safe to drive or not?
