Sometimes I despair.....

I noticed with horror today that the bag of peanuts I bought has a warning on it that it may contain nuts. If I were to take them back, do you think I would have grounds for complaint.
Things like this make a complete mockery of health warnings, it's like the boy who cried Wolf, if you put too many warnings, people will stop seeing them or looking for them.
As I said, sometimes I despair.
