I hate when this happens. I lost my walet once with arount 500 in cash plus all my debit/credit cards, driving licence.....everything.. I`ve noticed that I don`t have my walet at home after 4-5 hours since I lost it.....I went back to the place where I thought my walet fell from my car`s door pocket and guess what...after spending around two minutes looking around in dark and rain, from the second floor of a bulding , a man is shouting if I lost something.... And he returned my walet....What a nice man. He only took £20 I have offered for beers. It was an english man.
