I really hate being drunk

[librarian]

I have no idea of how I got home last night

That'll be the "beer scooter", not one of those Scooter Man things but a mythical mode of transport for drunk people.

"I've got no idea how I got home last night, I must have got the beer scooter."

And if you know you had £50 in your pocket you'll wake up at home with about £3.76 left. If you know you had almost no money you'll find a cashpoint receipt for a £50 withdrawl and only £3.76 in your pocket.

It's magic.
