Iosevka, a variant with slashed zero.

I went to one of these wanky places in London and had to use my phone light to illuminate the menu sufficiently so I could see it, thanks to those shit light bulbs they insist on hanging everywhere. There are dozens of them and yet they give off no light… wtf is the point.

I had an identical experience with some other networks. It was some time ago, so difficult to recall fully, but I believe restarting my phone regularly was helpful. It may just have been that patience was required for the network side changes to be propagated, but the issue was resolved after one of those restarts.
