Spell it as you say it!!

I was in the bank this morning ,paying in the weeks takings when two lads at the next counter wanted to withdraw £2000 from his account ( they were so loud ) , the cashier said " if you could fill in this slip please " and write in words the amount you want to withdraw .

one lad said to the other ,how do you spell £2000 , he then said ....t w o       F o u s a n d

i just smiled to my self
