I was going to put in the fact that its probably (what you guys call) 'soda', but us Brits call it 'coke'. I know it may sound daft to you but any soft drink is 'coke' here!

The reason I didn't is because I didn't want anyone thinking I thought this guy had some 'alternative' habit going on...

Though having said that I'm probably gonna get flamed with 'why didn't you just say 'soda' then? hahahaa
