How much is 1 yard of fabric ?

At a fabric store, a pretty girl spots a nice material for a dress & asks the male clerk. How much does it costs? “Only 1 kiss per yard,” replied the male clerk with a smirk. “That’s fine,” said the girl. I’ll take 10 yards.” With expectation & anticipation written all over his face, the clerk quickly measured out the cloth, wrapped it up & then teasingly held it out. The girl took the bag & pointed to the old man standing beside her & smiled “Grandpa will pay the bill.”
