Years ago on TV, I saw a feature about what to do if you find a partial dollar bill. They took it into the bank, it was put on a grid, and the value was calculated and paid out. Wanting to see this process for myself, I took the partial bill into a bank.
The first two people didn’t know what to do with it. The third person, clearly a genius, told me I needed the other half of the bill. The fourth person told me I needed at least 75% of the bill and that they don’t send them to the Bank of Canada until they have 100 of them.
So I left the bill with them, expecting to wait about 80 years to receive my $2.50. A few days later, they phoned and told me to just come in and get a replacement $5 bill. With it, I bought a lottery ticket.
