How much does it cost to ‘Spend a Penny’?

August 17, 2011


I was in London recently and at the Waterloo East station, it costs 30p to enter the toilets. Being a maths teacher, the natural question to ask is:

If you were to put a money jar next to your loo and put 30p in each time you used it, how much would you accumulate in a year?

Let’s take some answers in the comments as rough estimates please. There is of course one significant (and very personal) variable in this task! Without being too graphic, I wonder just how variable this is?

If you’d like to help with a short, anonymous questionnaire, perhaps you wouldn’t mind filling this in:

    I’ve never counted but suspect my CV is quite high. There is a further thing to consider: whether people would wait longer before using the smallest room if in addition to that 30p they’d have to negotiate their way (bags and all) through that little turnstile…
