Thanks for the comments guys. I think that was the worst airline sandwich I’ve had. Sabena used to have some pleasant ones, and occasionally SNBA and certainly VLM, but that took the biscuit for being foul! My Mum had egg mayonnaise and she said that was OK.
Must be absolute LUXURY when compared to the rolls they gave us on Tarom in 1989. These were like cricket balls!! You don’t have to risk bringing a weapon on board when they happily give you a roll that you could bludgeon someone with.
