Had a complete Walt in an airline I worked for. Cabin crew wallah.
Swore blind he was a Gulf War 1 hero. Listened to his stories with an internal smile.
Used all the right words straight from Andy McNab's books. Told me how he "tabbed" all the way from central Iraq to the Syrian border, fearful of being "slotted" at every turn and how he "slotted" several Iraquis in the back of a truck in order to be able to get past it.
Fortunately I'd read the same books that he had and I just thought "tosser" instead of the "WOW" he was hoping for. Naturally I was cautioned about talking about it for security reasons.
They're all over the place, beware!!
