Diolch yn fawr iawn, Trefnydd, for that answer. Can I also extend my thanks to the Minister for Social Justice for her letter on 10 November to myself on this very matter? Members will be aware of the work of Guide Dogs Cymru, who are campaigning to end refusal of guide dogs entering businesses. When I met with them in the Senedd a few weeks ago, they told me about guide dog owners being asked to leave some well-known establishments, with particular recent examples of places like Tesco and Premier Inn. These businesses do operate here in Wales. I understand what you've said in your initial answer, Trefnydd, but can I ask you what the Welsh Government can do to send a strong message that, in Wales, even one refusal is unacceptable? How can we send that message to ensure that in our nation we have an open-doors policy for guide dogs?
