South Africans are endlessly inventive.Especially people who have to figure out how to survive. A Garage Owner in Mitchell's Plain, an area subject to the aquisitive habits of tik (crystal meth) addicts, was sick of thugs breaking into his store to steal tools, etc. So he put the word out that he had a lion which would attack anyone that tried to climb over his fence or break into his business.
He has had no break-ins since.
