FOR OCCASIONAL USE! Just so you know - this app constantly weighs up what it wants to charge you. What might be a sensible scale at one time of the day can be crazy, immoral?! at others. Try ordering one from a festival for example! An algorithm factoring time, demand, location? If it deems charging you extra for whatever reason is ok, it will bcs it can. And, as you wait, your journey request will often then be ignored/cast off/pinged about by uber drivers that don't want your low cost fare.
