Old Soul, this reminds me of my experience back in  beautiful Lubeck Germany some 55 years ago with our little gang of USASA--  our favorite bar for dancing and meeting girls was the "Riverboat", an actual old river boat  tied at the dock, with live bands and two levels of dancing.
Their cover charge was a mark, officially a quarter but actually close to a dollar in buying power--There were always long lines at the entrance, but they waved us "Amis" right in without  having to wait or pay the cover charge--  they knew we'd end up spending plenty  of marks  for our Ratzeputz, Steinhagers, Escorial Gruen, etc. on top of our bier.  Besides that the girls thought we were good dancers.  chuckle  
PS-- Kudos to the RG headline writer here who avoided using the awkward term "alum" as seen in the print edition.  He's a  UO graduate, an alumnus, not a "double sulphate of various metals", whatever that means for "alum". chuckle
