Amnesiac is walking past a stationary middle-aged man who suddenly bursts into life when a big car rolls up and parks.
Man: [said exuberantly while putting both hands to temple in salute, smiling broadly and inclining slightly towards the driver]: Itfaddal ya basha! Saba7 el-fol! Ezzay el se77a! [Top of the morning, sir! How are you!]
A milisecond later after righting himself and out of view of the driver:
Koss ommak. [Fuck you].
