And now this is happening in US:

The interesting things are the comments.
While I personally faced the "what is your destination" call, on being told that it's to Kempegowda Airport, only to have the driver ask me to cancel the ride because "no oil for airport, saar" ie long distance.
Just today a colleague told me he was asked for tips/over the Ola bill too. While it got resolved over call for Ola customer care. It might not work for Uber which has only email support.
So how long before the "striking drivers" go back to the same old tactics people despise - not turning on AC, extra for AC, asking for cash and/or extra above the Uber price.
