If you’re traveling in Westminster, and your bladder is incredibly full, there’s a text message service that will help you find the closest toilet.

According to Reuters:

Anyone who sends the word “Toilet” to 80097 will receive a reply giving details of their nearest public convenience.

The service is available across the Westminster, an area that includes many of the capital’s most popular sights, such as Big Ben, Trafalgar Square and Buckingham Palace.

What a relief, eh? Just be advised that each text message will cost 25 pence. For heavy drinkers on the go, you may want keep down your costs by asking some of the locals where the bathrooms are located instead.

Would you use the “SatLav” toilet-finding service if it was offered in various locations?
