Every evening I put all spare change from my trouser pockets into a large glass jar next to the door. Once a year I reedem the money and have a really nice dinner.
Do you count the change before you redeem it? That is a huge time-suck for me, and I hate doing it.
Also, I feel really bad for the cashiers that are unlucky enough to have all that change dumped on them and are forced to count it all. Some banks have change counting machines, but surprisingly, many don't and the change is still counted by hand while you wait.
Are you serious? If you take it to the bank, they have change counting machines. Depending on how much you bring in, it takes about 1-5 minutes for the machine to count. In the US we have a company called CoinStar that has kiosks in every major grocery store chain which does the same thing. They take a small percentage, but we're talking about coins here, so it's probably less than a dollar per transaction.
