Unfortunately it’s probably prudent to ask your kids/grandkids to dump their take on the kitchen table and then give it a going-over, pitching anything suspect and pocketing any Snickers or Three Musketeers chocolate bars.
And Twix bars.
Yes, we are all trained to look over the candy. I just suspect that the actual instances of tampered candy are very few.
Also, I like your suggestion about the Snickers and 3 Musketeers. Very prudent.
