With today's snow in vatious airports in Europe and at Heathrow, there are multiple reports of passengers being kept for hours in planes without food and drinks due to BoB. One angry passenger said that cabin crews didn't know what to do as this was not in the manual. Another reporting that the pilot tried to order food with his credit car to be brought to the plane. It shows that the whole set up is a complete mess and does not allow for service recovery when it is neede (limited stock and supply belonging to another company).
