The Sales Tax

In one store I was about to buy something for $20, but the lady said, "$21."

I said, "It is written here-$20."

She said, "There is tax!"

Then she asked, "Where do you come from?"

I said, "India."

She said, "In India there is no tax?"

I said, "Yes; there is."

She asked, "Then why are you surprised?"

I said, "But this is on sale."

She said, "When something is on sale, there will always be sales tax."
