Pizza Peril

It is your first day of work at Catwalk magazine, a dream come true.  You are starting out as a lowly editorial assistant, but if you're patient and enthusiastic, then maybe one day you'll be flying off to Milan and Paris to check out the latest collections.  

However, that is still a daydream.  For the moment, you are the assistant to the glamorous Catwalk editor, Corey DiFerro - one of the toughest people in the business.  People say that she chews up designers, photographers, receptionists - and probably - editorial assistants - and spits them out.  And you never did find out why the last editorial assistant at Catwalk lasted only one day.

You're outside the main editorial office when the door opens and someone calls to you, "Ms. DiFerro wants you - NOW!!

Inside, there's a group huddled around the main table.  You recognize fashion designers, supermodels, two pop stars, photographers...and Corey DiFerro, looking you straight in the eye.

"Right. Do we have your attention?  Look, we are off on a photo shoot in half an hour and we need some lunch first.  Pizza - it is quick.  DaNoi down on Seventh Avenue does not deliver, so I want you to go out and get some for us.  Plain cheese only.  Now, how hungry is everyone?  I'll call your name and you tell my assistant how much you want."

Scala twins?"

"One slice each."

"Art department?"

"Two pizzas."


"Half a pizza."

"Copy editors?"

"We'll share one pizza."


"Three slices."

"Steve, our faithful driver?"

"One - one pizza, that is."

"And I'll have one slice," says Ms. DiFerro.  She hands you a roll of bills and sends you off saying, "They only take cash.  Don't take too long."

On the elevator down, you count out the cash - 90 exactly.  Will that be enough?  You don't have any cash of your own in case you run short.  Anyway, you do not have time to stop for more money.

At DaNoi you're standing on tiptoes to see over the other customers.  Each pizza is cut into 12 slices - no exception.  And the person ahead of you has just paid $36 for two pizzas.

It's your turn now.  Will you have enough money - and will you have a job tomorrow?

 And here are the winners from last week.
