Owners lack of customer attention

I left my car at the service station's car wash and was told that my car would be ready in 1h30mins. Upon my return the car was not complete and I had no time to wait any further. I approached the cashier for a refund and the owner was then contact as a refund on a debit card could not be processed without his permission. When he appeared, her addressed me asking me why is it that I was not willing to wait (refer to the time frame I had my car at this place) and understandably that they only have one person working on washing the cars, however this is an operational issue affecting customer service. The owner then proceeded to tell me that he will now have to take the employee for disciplinary (which actually means he directly threatened their employment while continuing to disregard my dissatisfaction). When I proceeded to tell him that I was not appreciating all this, he actually made a call and walked away from me telling me I will actually return. Well guess again... there are 3 other service stations around this same place and I would suggest to anyone who wants to avoid such service to not waste their time at this place.
