Free Almonds

The day care bus driver drives with a bus full of senior citizens down a country lane, when a little old lady taps him on his shoulder. She offers him a handful of almonds, which he gratefully munches up.
15 minutes later she taps him on his shoulder again and hands him another handful of almonds. She repeats this gesture about 8 times.
After the 9th time he asks the lady why they do not eat the almonds themselves.
She replied that it is not possible because of their old teeth. They can not chew them.

"Why do you buy them then?" he asks, puzzled. Where upon the lady answers,
"We just love to lick the chocolate around them".
