This might be easier than refusing permission every time - it sounds like I can just not click it. I really dislike location permission things. I don't know what location will be shared, I don't use anything that needs a precise location, and I don't ever want to share my actual location. If location permission things showed me a map with where they think I am and let me click a (vague) location to share, I might use them, but currently to find nearest stores or whatever I just type in a postcode or use their map.
Edit: this has prompted me to go find a way to turn off location permission requests in the browser settings. It turns out you can do it under Privacy and Security > Site Settings in Firefox and Chrome.
