I was told that I would be charged $ 300 because someone smoked in the truck (which we had for a total of 2 hours). No one smoked in the truck and I was spoken to in a very demeaning manner which strongly suggested I was not telling the truth. The young man who drove the truck is a periodic smoker but did not smoke inside the truck. He and his helper smoked a couple of times outside the truck. Any smell of smoke either came from clothing or perhaps a prior user. The agent at discount agrees he never saw anyone smoking inside the truck but was certain that someone had been smoking there. Our treatment and the attitude of the Discount staff was absolutely outrageous. I should point out that I rented Discount cars for many years and changed to another company because of poor service. This is yet another example of substandard service. y
