i predict a riot!
A shout you use when you're so busy you can't think straight. It's like saying 'I can't handle this anymore!' but with more swearing and less sense.
I predict a riot! I have 20 orders, no coffee, and my shirt is wet.
I predict a riot! The oven is broken and I have no idea what to do.
I predict a riot! I dropped a tray and the customer is screaming.
