There are a few: the famous case of Mr Squirrel, who purchased some plastic envelopes in a paper bag. In a short time the paper bag had rotted and the plastic bags also aged rapidly. In a couple of US cases witnesses have bought Coca Cola. I think the bottles were thrown away when empty. There are more cases of people who have had meals at cafes and restaurants that no longer existed at that time, but unfortunately the evidence was somewhere in their digestive systems by the time they realised what had happened.
