We were on 2 separate westjet flights that the flight attendants announced that we had "a special guest onboard with nut allergies & please everyone refrain from eating anything with nuts in them". We had nut chocolate bars & granola bars with nuts as our snacks, so no snacks for us those 2 flights. Now we take nut free granola bars & plain chocolate or yogurt as snacks just in case. Also we were on a flight that had a small dog & a passenger was allergic to dog hair, instead of moving the dog & owner they moved the passenger to the back of the plane. She was not happy.
When they started the announcement about " a special guest on board" I thought oh what celebrity is riding home with us. Lol
