Maybe one out of one thousand people he approaches on the street will give him ten euros or more. He probably figured that
you didn't quite get the monetary value of the currency, hence the trying to fool you into depositing some more of the
good stuff in his lap for free.

I gave some money to a begger who approached me when I was camped out in a trainstation's main hall some hours
before the first train was due to appear. As he was making his way around the station's few inhabitants at that time,
I lost sight of him. About 90 minutes later, he got up to me again, as had he forgotton my face and the fact that I
actually gave him money already. That pissed me off.

I have just realised that it was 10 cents I gave him.... Which is what I intended

Round here they work in flaming gangs...camped out round the town centre...

I know...I can be kinda confusing..
