Just returned from a lovely day trip to Vienna. Spoiled by the 'scam' which is taking place at the Underground music toilet next to the Opera House. Customers deposit correct coins into the turn style and try to enter but gate doen't open. A woman dressed in 'muslin' veil appears and gestures ( no attempt at any language) that you have not put in the correct coins but does not attempt to rectify the problem. but demands more money before the gate will open..
In the five minutes I was there this happened on four occassions thus my estimate is that they are making at least 50euros per hour easily!!! What a rip off, especially as the toilets at the Albertina Museum just round the corner are free and much cleaner. Help stop this scam, don't use this toilet.
