The breakfast perk is really unknown to check-in staff. Just had the most weird conversation with the check-in person at Radisson Blu Scandinavia Copenhagen.

"You've been upgraded to Business Class" (this after a long telephone conversation with someone who told the check-in person I should be upgraded)
"Thank you. I suppose my breakfast is included as well?"
"It doesn't matter, Sir, your company is paying for it."
"I know, but they shouldn't be paying for it since I'm getting it for free."
"But you are not paying for it, your company is."
"No, they're not, as it's supposed to be included."
"It's included."

Let's see what happens tomorrow at check-out. I've yet to be impressed with CC. It's rubbish.
