A brothel in Berlin, Germany has hired a 70-year-old grandmother to be its bouncer. And her boss says the woman is right for the job.

Wiltraud Hotzl, also known as "Mumsy," has no trouble turning away drunks and other undesirable clients who never argue with the aging bouncer at the Fraulein Mueller brother in Hermannplatz, Berlin.

The brothel's owner, identified as Johan Vepsi, 41, said, "She's got the business perfectly under control. Mumsy is far and away the best for the job."

He said "Mumsy" was very good at ensuring that customers are well-behaved and is even effective in settling disputes between the prostitutes.

Vepsi adds, "If she hears of a squabble between the girls, she will shout 'children, all quiet on deck please'. Total silence always follows."
