What can I do for you? 

 I'd like to check in, please. I have a reservation under the name Anthony Roberts. 

Alright, Roberts. Oh, Mr Roberts. We've been expecting you and here's your keycard to the presidential suite. 

 But there must be some mistake. My reservation was for a standard room. 

 Are you sure? Let me double check.

 Yeah, here. This is my confirmation number.

All right, Mr Roberts, there seems to be a mix-up. Unfortunately, we're over booked at the moment.  not to worry. We're pleased to offer you a complimentary upgrade. 

Presidential Suite, baby.
