Another little tip, if you have any loose english £1 coins in your pocket after you board your final flight to Manila, just make sure you take them out and put them in your bag right at the bottom, not in one of the pockets. Because when they search you at they airport they'll ask you to take them out, then they'll just smile at you and say "souvenir" and you'll more or less feel obliged to hand them over, that's if you don't want to be delayed that is.
