Anglophone?

I stopped by the local Monop to pick up a couple of things and had an odd exchange with the cashier. It took place in French, here’s a rough translation.

Him: Bonjour
Me: Bonjour
Him: (after a few seconds): Do you speak English?
Me: Yes
Him: Are you Anglophone?
Me: Yes
Him: You’re not American?
Me: Yes
Me: Did you ask because of my accent? (even though all I had said was “bonjour)
Him: No, I’ve seen you a couple of times and you have a certain style.

I’m not sure how I should interpret his comment…
