haha, I remember last year i had some money that wasn't legal tender anymore, went into quite a posh bank and they said I couldn't change it there, and would have to go to the government bank.
It was also tuesday market day, which meant the world and his wife, their next door neighbour were queueing up. There was even a guy with a goat on a lead in the goverment bank !
took about 15 mins but they changed it.
