Free Access to Toilets in London Stations from April

I'm glad that public toilets are free to use, not just in U.K. but basically in every country possible. Today I drank a whole 1.5l bottle of water, during a bus ride of like one hour it became insufferable to hold it in and then when I finally got to the station I ran to find the nearest toilet.

One of the toilets on the ground level was out of service so I had to go upstairs and then to the level below.. water is good but drink too much and it'll leave you in pain.

If the toilet was like "insert €/£/$_____" you bet I would.

they should be free to use, and they should be accessible also. The last thing you want in the crowded city streets is people relieving themselves on shop corners and against post boxes
