Can remember sitting in NGU pilots area whilst on a charter. The UHF radio ran hot, H.E's beer I expect was very cold, and all the charters about to depart were cancelled as the aircraft needed cleaning.
Yes aircraft should be cleaned but why Cx flights about to depart with pax already waiting?
This is just one of many interesing things I saw.
Unfortunately other things were somewhat unsafe.
Hope parties have learnt and fly lawfully now.
