It's quite un-British but quite human.

One of the branches of Savills plc, a leading global real estate services provider based in London, has seen fit to issue a memo admonishing its staff not to have sex while in the office.

The memo from a Savills director was addressed to the 50 staff at the firm's branch at Sloane Street in London. It came about after plumbers seeking to unblock clogged toilets or loos in the branch discovered the cause of the blockage was a huge pile-up of used condoms in the sewage pipes.

The branch has a staff of just 50 persons.

A story in The Daily Mail said a leaked email, said to have been sent by a senior staff member at Savills, noted that plumbers had spent seven hours figuring out the cause of the problem with the branch's perennially clogged toilets.

Richard Gutteridge, director of residential houses, sent a memo saying that after working on the toilets, plumbers eventually found a mass of used condoms had caused a blockage in the sewage pipes, preventing them from draining properly.

Gutteridge's memo warned the branch staff that "obviously such activity should not be taking place in the office."

Gutteridge lamented the plumbing work cost the office a considerable amount of money.

"Please, can we be considerate to the ancient Sloane Street plumbing going forward," he asked in the memo.

In its defense, Savills said the branch shares its plumbing with other firms in the same building, meaning that Savills' staff might not be the only source of the used condoms.

There is no word if any of the staff were disciplined for their un-British behavior.

The pipes have been unblocked and the toilets are functioning perfectly.

But for how long, we wonder?
