In the hotel

One of the advantages of staying at the hotel is the anonymity it provides. So that occasionally, one hears conversations like this one (reproduced here in its entiretly):

Speaker 1: So, I've figured out exactly what you should do with the rest of your life.
Speaker 2: Tell me.
Speaker 1: You should totally finish medical school. But then you should make it a point never to practice medicine.
Speaker 2: Why's that?
Speaker 1: That way, when you come south to work as a gunslinger here in Mexico, you will totally have earned the nickname "Doc".
Speaker 2: Awesome!

I need hardly add that both participants in this conversation were male.
