Little Johnny walked into an ice cream shop and asked: "Do you have chocolate filled ice cream?"
The man replies: "We are out of that, sorry, we are almost out of every single flavor, do you want me to get you a vanilla filled one?"
Johnny replies: "Sure."
After that, the man asks for Johnny's phone and goes to back of the store. 5 minutes later, the man comes with an ice cream and Johnny's phone.
Johnny asks: "How much for the ice cream?"
The man replies: "Nothing, it's on the house."
After Johnny ate his delicious ice cream, he searched for his watch history. And then Johnny realized the flavor of the ice cream.
