Hilarious isn't it;  a chicken shop running out of chicken. If you haven't seen some of the videos of distraught chicken connoisseurs being turned away, I suggest you take a look. 

In all seriousness though, it is fascinating to see how a back office cock-up is handled by the front office. Sticking up A4 sheets up saying "we're out of chicken," isn't the greatest idea. I'm not marketeer, but I'm sure there is some kind of play into new markets/ new products that can be run here...
