I called a cab to take me to the cultural center in San Francisco. I gave the Uber driver that address for the cultural center. He seemed like he knew where he was driving, but then he made a turn down a one-way street. The guy apologized and told me that he was a little distracted. I could tell that he was distracted, because the entire car smells like marijuana. Car drivers aren’t supposed to use marijuana in the vehicle when they are on duty, but I could clearly tell that the driver had been smoking pot just before I got into the car. I don’t have any issues with marijuana, so I didn’t say anything to the driver until he took three wrong turns and ran a red light. I was very concerned for my safety and the driver was taking his good old fashioned time to get me to my final destination. The trip to the cultural center in San Francisco was supposed to take 17 minutes and I was actually in the car for almost an hour. I kept asking the driver if he was going the right way and he ignored my questions. He glared at me a couple of different times. When we finally stopped the car, the driver tried to claim that traffic was a problem. I knew traffic wasn’t an issue at all, and I did not give the guy a very good tip. I don’t know why he is using marijuana if the guy can’t handle his job and driving in San Francisco.
