For you. Your anecdote does not represent everyone's experience. This seems to be an issue a lot of people have, "well I haven't seen it myself so I'm sure this isn't actually an issue".

Cynicism is fine, but it's better to pull up the numbers than go by personal experience and anecdotes, because that's n=1.

my anecdata is that about 1% of the Uber drivers/delivery are different people that show up in the app.
