We got into an UBER at SFO with a Bangladeshi driver. His UBER X was not only FILTHY but he had the worst BODY ODOR!!! Since we were in a hurry we accepted his ride.
Believe it or not, while his interior of the car was filthy he had the NERVE to tack on $50 to our charge for a CLEANING FEE!!! to clean HIS dirt and BODY ODOR!!
OUTRAGEOUS!!! as there is no customer service number and no way to reach a human being to protest--YOU ARE STUCK WITH THE CHARGE.....so it seems the 'fraudulent' drivers can do whatever they want
