What should I do with condoms after use?

A Japanese tourist went to China and ordered a lobster for dinner.

When he finished eating, he asked the waiter:

What do you do with the remaining shrimp shells here? ''

You can do nothing but throw it away! The waiter replied.

Oh, no! In our country, we send it to the factory to make shrimp cakes.

The tourist ordered another orange and asked the waiter after eating:

What do you do with these orange peels? '

You can do nothing but throw it away! ''

Oh, no! In Japan, we send it to the factory to make jam.

So the Japanese ordered some chewing gum, chewed it and spit the pulp on the plate, then asked:

What do you do with chewing gum residue? ''

Oh, no! We threw it away! The waiter replied.

In Japan, we send it to the factory, make it into condoms, and then send it to your China.

The Japanese pay the bill after eating. When the waiter brought the bill, he asked:

What do you do with used condoms in Japan?

You can do nothing but throw it away! The Japanese replied.

In China, when we run out of condoms, we send them to the factory to make chewing gum, and then send them to Japan, the waiter said.
