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.
