I suspect the issue was that the gents toilet capacity had, effectively, been halved as the upstairs loos were only accessible to those who had paid for the hospitality option.
Definitely - there was even a sign downstairs saying 'additional toilets upstairs' or similar....not much use if the Barber Gestapo (identifiable through their mustard-coloured body armour and hi-tec bottle top detectors) are blocking the stairway though
