We visited Capri today via fast ferry from Positano. Purchased 4 tickets for the Furniculare (at €1.80 each). Handed over €20 to the man who handed back change and hurried us away before we even realised we had been ripped off! €3.60 change doesn't even add up to change from €10 so it wasn't like he mistook the €20 note for a €10 note. There was a huge queue otherwise we would've gone back and asked for our money #learningexperience.
