I don't understand the connection. Surely inflation hawks would want generally smaller bills? But even then only the stupidest among them would also think this could be achieved via printing specific denominations rather than interest rate and other real fiscal policy.

My understanding as an expat was the same as alasdair's - 2010-2015 I saw plenty of Germans drop a couple 500s to pay for hotel stays, major appliances, etc. Few people had a credit card and those that did didn't want to use it domestically. It's changing now but people still carry more cash and true credit card payments are still often impossible even as bank cards are now more common.

I guess you could argue this is also related to Weimar inflation, but I don't think it's so specific. Germany has seen multiple major regime changes in the space of one lifetime.
