Oh, I've broken plenty of plastic jars. Of course, I don't have quite so many unopened boxes to cushion their fall.
Has anyone seen (of course) one of those plastic trays at places like convenience stores? Do you ever take the change and have a peek at what's there or do you avoid it at all costs?
I've seen dimes and quarters in those "leave a penny" things. I don't know if people think they're tipping or are financially clueless. When I take my change jars to the bank about once a year there's like $200 in there.
