As usual Briatin is a world leader in this field.
We've been employing gangs of roaming monkeys in this country for many years.
We give them a uniform a clip baord and a peaked cap. Then they work as Security Guards, Bouncers (aka Entrance Executives) , Wheel clamping Operatives, Parking Enforcement Officers or Wardens and / or as Police Community Support Officers, some of the less intelligent ones find employment in local government as Outreach Co-ordinators, Social Workers and in the Refuse and Recycling Departments.
One council even employed some chimps in their finance office. You may have seen them recently in the news regarding a transfer of money to some 419'rs.
However generally we eschew the smaller breeds tending to concentrate on the Gorilla / Baboon variety.
