Uber rides: Is the passenger supposed to be the one paying for parking?

Everytime I request a ride to/from Junction mall, the drivers ask me to pay for parking. Surely this shouldn’t be the responsibility of the passenger?

I have my card attached to the Uber app so I don’t have to bother with cash and change so being asked for 50ksh to pay for parking isn’t fun.

Please let me know if this is normal or I’m being exploited.
