OK, I've booked a taxi for stupid o'clock later this week and have pre-paid it. Don't use taxis that often, but when I did, I generally rounded up the fare, pretty standard I thought.
But, now we're not supposed to be using cash, do I tip the driver in cash anyway, or what? I've had cash in my purse since March, which I used in the self service till yesterday annoyingly, so I'll need to go and get some more if I'm going to have cash to tip.
What are people doing/what would taxi drivers prefer these days?
