I had bought perfume which was in sealed bag at Gothenburg . Since British airways forcibly checked in my cabin bag I didn’t have a choice but to step out to claim baggage . I had to go through security to enter bag who opened my sealed bag to do some thorough check and did not put it back into sealed bag since I had no transfers. British airways then delayed the flight by 3 hrs and changed the gate which forced me to go through security check again . Vivian was very rude to steal my perfume claiming process when it was her own fellow colleagues who made the mistake and refused to let me go back from security with my perfume .
