I’d sit down and see a similar sticker: “Want a beer? Chat with us!” with a chat code beside it. I’d unlock my phone, open my chat app, and scan the code. Instantly, I’d be chatting with the stadium bot, and it’d ask me how many beers I wanted: “1, 2, 3, or 4.” It’d ask me what type: “Bud, Coors, or Corona.” And then it’d ask me how I wanted to pay: Credit card already on file (**** 0345), or a new card.
