Personally I have had tips from $2 all the way to a $20 bill & have NEVER opened the door for any1. The day taxi drivers open doors for pax is the day I “may” reconsider.
Uberx is a revolutionized taxi. It’s not rocket science so don’t complicate it
UberBlack & SUV are there for those who desire their personal chauffeur
These pax are already paying Walmart prices for a 5-star service. Anything else is just pushing it…
