On December 29 I rented a Nissan Spectra from Thrifty Car Rental (Buffalo, N.Y.) at their airport location for one week. Upon returning I was astounded to find out I had been charged an additional $150. for smoking in the vehicle. I don't smoke and no one else was in the vehicle other than me. I argued my case and have spoken and written to them without success. What a low life way of milking an extra $150. out of once were loyal customers. Goodbye Thrifty!
