There is no such thing as a free lunch, i knew that much. But museums?
When i was at the National Gallery in London, they made it pretty clear that free was not what it said on the label and when i went in without paying an extra "donation" of three quid for the "free" audio guides, i got more than just a grumpy look (Did you know swear words can fly?) So, be careful when people ask you to donate .. You might not be able to refuse their "offer". Hey, do not mention that to the organ "donation" organisations .. Body snatchers revisited?
Anyway, with this in mind i got a bit suspicious when i looked at this photo of a Deutsche Bahn info sign i took earlier this summer. Is the travel information you get there really free or just "free"?
