I made a reservation earlier this week , but I have to cancel it .   No problem , sir . Just tell me your name , phone number , and date of reservation .   Great ! I'm Rudy Randolph , 818-555-1234 , and my reservation was for April 9 to 15 .   Okay , sir , let me hit the delete button , and your reservation will be cancelled .   That was nice and fast . Thanks .   Not at all .
