Some of those things do go bad after a while. I don't know if all of them do. Nor how long it takes. The wife and kids save them, I mostly throw them out when I find them and have no idea how old they are (the family saves them, but doesn't label them with dates, not all come pre-dated). Doesn't matter if I throw them out, there will be 500 new ones tomorrow! Just yesterday I went to Arbys and brought back a Junior sandwich for the wife. I asked them to put a sauce packet into the bag. When I got home there were no less than 23 sauce packets - I'm not kidding! That would have been one drippy sandwich with all that sauce. Do people really eat them that way?!
