Of course ma'am. The police who insisted on a whole new security system for the entire shopping centre, got a little carried away.

Waiter! There is a tiara in my soup!

Wonderful, madame! You are the restaurant's princess for the evening!

Waiter, there's a cookie tin in my soup!

Yes  it's for dunking  so quickly pull it out before it dissolves. 

Waiter, there's a false nose in my soup!

Yes, we ran out of real ones.

Waiter, there's a guitar in my soup! 

Pardon - we're a little short-staffed, so you must supply the dinner music yourself.

Waiter, there's a butterfly net in my soup!

You said you were nervous about trying a new restaurant and had butterflies in your stomach.

Waiter, there is a rock in my soup.

My apologies, sir... we were making Stone Soup and the chef must have forgotten to take the magic soup-stone out.  

Waiter, there's a needle in my soup!

Drat, you found it already? That really takes all the fun out of serving "Haystack Soup".

Waiter, there's a fidget spinner in my soup! 

Yes, sir - it's to help you focus on the soup's flavours.

Waiter, there's a Rubik's Cube in my soup!

That is the free gift offer to liven up our basic clear consommé! Each turn of the cube allows you to visualise a new combination of  different delicious soup ingredients to dream about, after your discharge from the  gastroenterologic ward next door. 

Waiter! There is a stethoscope in my soup!

I am a doctor, that stethoscope is in in a sterilization bowl, and you are in the ER for a possible (and getting likelier by the minute) concussion.  I would not advise you consume that.  

Waiter, there's a lamp in my soup.  

Oops, sorry, sir — that was supposed to be lamprey soup. Our chef is a little hard of hearing...

Waiter, there's a Christmas bauble in my soup!

Yes, sir, our chef likes to decorate his meals at this time of the year.

Waiter, there's a small Narnian dagger in my soup!

Er Madame, try as I might, I can't see anything in the soup that may cause you any worries. The chef took good care to prepare this lusciously nutritious soup, without any unusual herbs that would cause you to experience out of this world adventures.

Waiter! There is a hunting horn in my soup!

Yes, you did order game soup, I believe?

Waiter, there's a chess piece in my soup!
