The waitress excuses herself momentarily and turns to the newcomer; her smile and eye-sparkling never wavers as she speaks to her second customer. "Yes, actually. We carry almost everything... no, it's not out of convenience for a role-play, I don't know what you're talking about. Now, would you like a window seat or a non-window seat? And how much sugar would you like with your cappuccino?"

EDIT: After waiting a couple of minutes with no visibly forthcoming response from the blonde girl, the waitress turns back to her first customer.
