Fly in the Tea

A person went to a restaurant and ordered a cup of tea. A fly fell off in his tea. He asked the waiter to replace it. After a while, the waiter brought a new cup of tea. What should be the strategy of the person to identify whether he has brought the same tea or not. He can take a sip if he wants.

  2. He puts something like salt in the tea and mixes it so that he can identify with a sip. Then he sends the tea back. This way, when he takes a sip from the new cup, he can immediately tell.
