I returned a rental on Saturday after renting car for a month. On my way to drop off vehicle, I gave my Nephew a ride. After dropping him off I noticed a smell in the car. He had weed on him and it left a lingering smell. I later talked to him about it and I promise this will never happen again. I will make sure no one is in a rental vehicle with weed on them. I was charged $400 for cleaning the vehicle because they said I smoked in it. I did not or no one else smoked in vehicle. I talked to other people and they said the smell will go away on its own after the windows are left down for about an hour. I didn't smoke in vehicle and I realized I was responsible. Just wondering if cleaning vehicle can be reduced to around $100. Again I know I'm responsible for the vehicle but I just can't afford the $400. Please help. Thanks
