Taxi drivers in Boston have a commission too, they have to rent or lease a medallion for hundreds of dollars a week (and it's much cheaper now - thanks to Uber & etc).

In large US cities they also have to "tip-out" the hotel doorman and the dispatcher so they can get the high value riders.

Depends on the city. This is far from being the standard, even in the US.
