Went to Vegas last week with some friends. My wife signed up for Uber while we were there and we took an UberXL van from the Venetian to the airport around noon (six of us). This was our first WE paid for it (we reimbursed our friends the other times using it there since we didn't have an account). The next day when we got home a Uber charge of $139 showed up on our account for our ride from the Venetian to the airport. Looking at the receipt from Uber there was a "surcharge x 3" that was about $90 of the total charges. Anyone know what this means?? TIA
