Has anyone here actually used Bitcoin/Lightning payments at a real store through Square yet?

I keep seeing news about Square enabling BTC payments and I’m curious how practical it is right now in the real world.

Do you need Cash App/Strike specifically?

Do merchants usually know they even have it enabled?

Can you just scan and pay instantly or do you still have to awkwardly ask the cashier first?

Would love to hear some real experiences from people who’ve actually bought coffee/food/etc using Lightning at checkout.
