Hi . I ’ m here for flight 514 returning to Beijing but the board shows there is a delay.How long of a delay is expected ?   So far it looks like we will be leaving two hours late , but keep checking the departing flights status board just in case .   Do you think it ’ s safe to leave to get a quick bite ?   I think you should stay in the airport . Even though the delay is expected to be two hours , the flight departure could be announced any minute . Who knows ?   What seems to be the problem ?   It seems there are some loose bolts on one of the wings . It happens all the time . No need to worry .   Umm ... You know ... Actually I was thinking of trying another airline . No need to hold my seat .
