From ChatGPT:

Okay, honey! 🎀 Imagine your favorite shopping mall. A vending machine is like a mini-store in a box. When you pop in some coins or swipe your card, it's like giving the machine your credit card to buy something. Once it knows you've paid, it gives you your snack or drink, just like when you get a new purse after paying for it. Easy-peasy, right? 💄💅🏼🛍️
