OP This is one of the most disgusting photos To sit in that seat (let alone sleep,( I couldn't have done it) is the height of disregard of normal , customary .service delivery.,

I would have demanded a move even to F if CW was full or a downgrade to lesser class with a FULL refund or a DIVERSION ! Sounds radical but no way am I going to sit in the vomit for fear of catching something
Go after a full refund and an apology from a senior manager Enlarge the photo as a paper copy and send it to Mr Walsh and Board members.
