Exchange currency in a bank - an analogy

Posted at request of HS

Mr ABC is American currency expert. As there are a lot of counterfeit in the US currency, sometime money changers or even banks will ask Mr. ABC for verification.

Now, Mr ABC would like to tour Europe with his family and, being not the expert in the EURO, he decided to exchanged the EURO in the Big and reputable Bank, CAR Bank.

Soon after, Mr ABC discovered that some of the EURO are counterfeit. He went to CAR Bank and complain about it (the counterfiet EURO).

The Bank response :
1. You are a currency expert and you should know how to differentiate the counterfeit from the real !!
2. Buyer Beware - you should have checked all the pieces of the EURO before you leave the Bank, how can you just trust the bank teller.
3. No body asked you to come here and nobody put the knife over your neck to change the Euro.
Comments 2 and 3 are self explanatory, but I want to mention about comment No 1.
Being an expert in American currency does not equal to expert in currencies. So even though an investor is familiar with some financial product, no one should expect him, thus, to know all the financial product, in this case I refer to HN2, HN5, Minibond, Jubilee 3 etc.
