We drop change into a change bowl. When it starts getting full, we use the contents of the change bowl to pay for take out. This doesn’t happen very often because 90% of the time I just use Interac debit to pay for stuff, so my need to deal with cash and change is pretty infrequent. I pity my poor American friends who don’t have access to a sensible non-cash payment method that’s accepted even at stores that can’t afford to accept credit cards with their 3% fee.
