A guy asks for a pack of cigarettes from behind the counter.
Me: “Alright, can I see your ID, please?”
Customer: “Why?”
Me: “Because it’s the law. Anyone buying tobacco has to show ID if asked.”
Customer: “Why?”
Me: “Because the law says you need to be at least twenty-one to buy tobacco products in the U.S.”
Customer: “Why?”
Me: “Because before 2019, the minimum age was eighteen, but Congress raised it to twenty-one nationwide to cut down on teen smoking.”
Customer: “Why?”
Me: “Because data showed that most smokers started before twenty-one. If you push the age up, fewer teens pick up the habit, and smoking rates go down overall.”
Customer: “Why?”
Me: “Because nicotine is addictive, and the earlier you start, the harder it is to quit. The body and brain are still developing into your twenties, so starting younger increases long-term damage.”
Customer: “Why?”
Me: “Because nicotine binds to receptors in the brain that regulate dopamine, basically rewiring your reward system. That’s why people crave another cigarette even when they know it’s harmful.”
Customer: “Why?”
Me: “Because the human brain evolved to reinforce behaviors that release dopamine, like eating or social bonding. Nicotine hijacks that system, tricking your brain into treating smoking like a survival need.”
The customer stares at me for a long moment. Then, without a word, he slowly hands over his driver’s license.
Customer: *Grinning.* “Eh, I’m just f****** with you. You’re the first one to last longer than my ‘why’ routine.”
I swipe his ID and hand him his cigarettes.
Me: “Great, now ask me why I still work here.”
