relative value of money
I think the question opens up a broader question about the relative value of money to different people. If, would you pick up:
a) a penny, no
b) 50 Euro note, yes
Then where is the cross over point in between?
Had an experience when living in France a no. of years ago, buying some bread. Was due some change (centimes) which I had thought had almost passed out of circulation, and in any case was worthless to me. Had started to leave & the assistant called after me for my change. Afterwards I felt that my behaviour had been a little rude and arrogant (bloody rich tourists!).
My position now? If I drop a penny, then I'll pick it up. If I see it lying in the gutter, then no...
