Brexit cake

I went into a restaurant recently. Once I was seated the waiter brought me a menu. It had all the usual things on it - red tape a la mode, regulation soup - so I asked about the daily special. The waiter replied, "Today the special is Brexit cake!"

"How much is that?"

"Oh no, you don't have to pay us, we pay you! You get a discount of £350 million - each week!"

"Well, what is it - what are its ingredients?"

"The main ingredient is sovereignty but going light on the red tape - and all the ingredients we use are locally sourced, we avoid imported ingredients as much as possible."

"Sounds really nice - how come it hasn't been on the menu before?"

"Well, I'll be honest with you, sir, not many of us think it should be on the menu now. Our head chef tells people not to order it, and most of the waiters say the same."

"Why?"

"Well, it looks and smells lovely, but it has an awful aftertaste."

"Still, for £350 million... Maybe I should order it and put up with the aftertaste."

"Err, about that money. If you check the small print you will find that you never actually get to spend it. In fact, not only don't you get the money but we will be sending you a large bill after you leave the restaurant."

"So if it tastes awful and is incredibly expensive, why is the cake on the menu?"

"Well, there was a bit of a bust-up in the kitchens - there's been trouble brewing for a while. A couple of the sou-chefs wanted to serve it. Mr Cameron, the head chef, said he would put it on just so they could see no-one wanted it."

"And he was wrong?"

"That's the funny thing, sir. Around a third of our customers order it, and order it for their children and grandchildren - without even asking if they want to eat it. They have to force it down."

"Doesn't anyone return it to the kitchens?"

"Oh no, sir. You can't do that - you can't change your mind."
