Hello,

I get your point, but now that cashless shops are becoming increasingly common, relying on a default value ("If this tag is missing, I should expect that I can pay with cash there") is probably not as reliable as it was before.

Most shops refuse the largest bank notes anyway, I don’t think that this should be a reason to hide that they accept the most common cash denominations.  Perhaps that adding tags such as "payment:coins=0.05€;0.10€;0.20€;0.50€;1€;2€" + "payment:notes=5€;10€;20€;50€" would make everyone happy here.
