Touring the city was a tour guide and a bus full of elderly people. 30 minutes into the tour, the guide feels a tap on his shoulder. He turns back only to find an elderly woman offering a handful of peanuts. With gratitute, he accepts and thanks the old woman.
Another 15 minutes and the same thing happens. This happens around 4 times. As the guide is offered again for the fifth time. He is now wondering, "Thank you, but why do you buy the peanuts if you do not eat them?", and the granny answers, "We just like the chocolate on them!"
