Fast food restaurant visit

Literally during my visit a few minutes ago to a fast food restaurant to order lunch:

Girl at register:  What would you like to order, Sir?
Me: I need just one minute please
Girl: *jokingly* So you one-minute man?
Me: *smile and nod head* No.  More like an hour, and even longer, man.  
Girl: *flirtatious smile*  So happy to hear that.

It seems to me she was flirting.  Or just a lively and funny exchange.
