Have cash on hand when dealing with taxis. Don't assume card terminals will work, or even that they won't skim your card.
You may say, 'That's why I hate taxis cos they scam you,' yet this thread has contains many examples of Uber(Eats)* scamming people too.
Why is that better? Cos it's accessed via smartphone for some reason?
Conjecture/Rant: There is a growing cohort of people who want everything to become 'frictionless'. They are even afraid to just talk to people, talk to girls, everything has to be through text or through an app. If they get their way humans will start to interact with each other more like machines than like people, hey, maybe even through APIs! Meanwhile, what makes life interesting 'is' friction between people and cultures.
