“You know,” I want to say, “that’s stupid.”
My mind races with the possibilities: put the barcode on the sack rather than on the bottle, use a clear sack, though which you can scan, don’t use a sack at all (saving some natural resources in the process), at the very least, just fold the sack over and don’t bother with the staple.
But I don’t say anything because I don’t want to look like a crank.
Last year, one of my son’s teachers would take a piece of lined notebook paper, copy it 25 times, then staple it to his sheet of homework questions 25 times and hand this out to the 25 kids. Palm to forehead.
He could just tell the kids to use a separate piece of paper. Or if he really feels he has to supply it, he could just have a stack of paper in his room.
Again, didn't say anything. No good would come of it.
