Some time ago, I had a problem getting in to a public toilet near the bus station in Caernarfon. There were two doors to negotiate, both needing the use of a Radar Key. You had to manoeuvre about holding both doors to try and get in!
Well, since then they have, sensibly in my opinion, removed the inner door. This makes it much easier.
The only problems now are the fact it was filthy on my last visit and the tap does not work! Come on Caernarfon Council, sort it out!
