Not this airline. A mouse spotted on board. Was a near midnight departure from Bangkok or KL. Can't remember. Once the delay was announced 80% of passengers ran to the lounge and anybody was let in. It was crazy. I complained that people were in here that shouldn't be. I had a DYKWIA moment and said I pay a lot for the privilege to be here in peace. Next thing I see is staff going around the overcrowded lounge checking eligibility and 75% of people start leaving. I then ask for a blanket, have them dim the lights and music and have a sleep on the sofa for a few hours. Mouse not found so put on a different plane.
