3 Sheets gets a 1/4 oz.

[3 Sheets To The Wind]

Silly human. Being an American my bank account was in US dollars. My balance would be in US dollars at cash machines, too. So I'd have to know how much I could actually spend

Yeah... I can see myself standing at the checkout going "Okay what's 76.83 x 1.56???"

Change it at the airport, just get a shitload of cash

Or just take out a good few hundred pounds and convert back what you don't spend
