The tour guide, called himself "Mr Hollywoodz", asked for 20% tip at the start of the trip. He gave us very less time to view the places and kept on insisting for tip every hour of the trip. We didn't get to enjoy the trip bcoz of his loud voice and over energetic (felt like he had too many redbulls). Beware of booking the trip from 6437 Sunset blvd tour group. After paying for 7 hrs LA trip no one would want to rush and complete the trip. Unexpected was 20% tip and very less time at every LA tour stop, roughly 30 mins he gave us to enjoy the places.
