Apparently, losing one's lunch in the back of a cab has become quite the thing in South Korea — and drivers are sick of it.
So much so that both Taxi Driver Associations in Seoul have joined together to instate a city-endorsed fine of 150,000 South Korean Won (about $175 AUD) for passengers that chunder.
A survey conducted in 2014 noted 42.5 per cent of all complaints lodged by Seoul's taxi drivers involved vomiting customers.
Here in Australia, you can be charged up to $50 extra for revisiting breakfast in a taxi.
So next time you think about catching a cab with Ralph after a Korean BBQ — maybe walk it off first, or it could be the most expensive meal you eat, twice.
