Xbot and you were at the supermarket, he was accompanying you for the shopping that your mother had asked you to do, he was pushing the cart and you were choosing the product, that's how it was done naturally now with robots

It wasn't until you went to the candy aisle to pick up something on your list that your eyes fell on a box of chocolate. You grabbed one and only because your money was so tight that you couldn't buy it.,to which Xbot saw him and approached the checkout, not only taking the chocolate, but putting everything in the cart, you were going to protest but he interrupted you

"I'll pay for it"

Robots were paid for helping humans.
