I USED to be a regular customer at this location since 2015. I've done oil changes, brakes, motor mounts, struts, wheel berrings, and numerous other recommendations. Over the last 5 years I've spent THOUSANDS of dollars at this location not to mention all the people I have referred. Today you've lost me forever as a customer because of an UNWISE decision to not accept $100 of coupons which I earned from being a loyal customer. Not mention slow service and the steadily declining customer service. I could tolerate a 2 hour oil change, but not working with a loyal customer and honoring coupons earned (when you used to) is where I draw the line. Real short sighted on the manager's part.
