I was standing in line to get through the security check in Munich on Monday very early morning, and the suit in front of me puts in all seriousness a bobby car on the conveyor (bobby car is at least in Germany a classic toy car for kids 2-5 years old). The lady of security needed to call the supervisor, because they feared the businessman could use the toy car in the plane and hurt passengers.
There was a little dispute between the passenger and the head of security and finally he was allowed to take it with him. The only requirement by the security was , that the passenger would drive on the bobby car to the gate. IMMD. Good that there are people with a sense of humor and of responsibility at this time of the day.
