When chatting with customers, what are some important things you can learn about them that may influence how much (or how little) alcohol you should serve them?
Explanation
Answer: D - When chatting with customers, you can learn important things such as how much they are planning on drinking, their mental state, and even whether or not they are on medication, all of which can influence their reaction to alcohol.
Learning to chat with customers about these things does take some skill (you should never just outright ask about these things, since doing so can come across as rude and intrusive). However, bartenders/servers often learn to bring up these subjects casually in conversation (“Hi. I noticed you have some medication out. Would you like some water?”), though a customer’s mental state can often be observed from visual cues.
