Happy Days

'Happy Days' is an expression they use here which basically is the equivalent of saying, 'great' or 'right on' or 'very good then'. Or something. Here's an example: 
"Could you please portion the cheesecake next?"
"Already done."
"Happy Days."
Anyways, today was all happy days - it was fairly quiet in the kitchen with only a few staff members on, the rest of them on holidays. I got lots done, and lots done right, and the environment was more laid back than usual.
