Your ID card , please .   Oh , yes . Here it is .   Do you want large ones or small ones ?   Four in hundred , one in ten , please .   Wait a minute , please ... Here's the cash .   By the way , I'd like to change some U . S . dollars to pounds and I want to know today's exchange rate .   Well , sir .
