If you are starving between flights and only have time to grab from their to-go cooler, don't bother stopping.  No one working the stand and the bartender refused to ring me up.  To the male bartender who was unnecessarily rude--acting like something is not part of your job is never the right response to a customer.  If you don't like being a restaurant employee, that's on you and it's no one else's problem.  Please don't take it out on the people who want to spend money at your establishment.
