Drinking Problem?

Is it wrong when your new manager...a manager who hasn't been in Phoenix but for 2 weeks approaches you with the following:

Manager: This isn't work related but I have a question for you.
Remi: (nervously looking around) uh ok.
Manager: (leaning in) "do you drink"
Remi: (now really looking around nervously and turning red) How did you know? Did someone tell you?
Manager: No it's just that you can tell with some people.
