So THAT's the secret behind the UK's drinking habits!I live in London and pay toilets are very much a thing here, although they've just removed the payment from the Tube stations.
If you get caught short almost all pubs will let you go there and there's certainly no shortage of those. The issue is you'll have to stay for a pint, which means you'll need the loo again, which means you'll have to find a second pub, then stay for another pint, and so on. It's a vicious cycle, you see.
Meanwhile, over at the Rover's:
"Get me a paynt'o'lagah Terreh! Actchally, it's been a hahd day, make it two paynts! I'm gonna need to use the loo more than once tonaight!"
(That's about the best I can do with the written phonetics of the Manchester accent)
