Be a bad person while using Uber

Uber you are ripoffs! Today I have learnt that it is not worth it trying to be a good human being. A very pleasant Malawian man was my Uber driver and I decided to treat him to lunch before the return journey. Uber decided afterward to charge me a surcharge of R280!! Yes!! for that privilege! I am disgusted. So I will never be nice again. It costs too much. A ride quoted at R355 turned out costing R633 plus the lunch costs and a R50 tip! I am so over Uber.
