> You are not a representative sample. If you look at the statistics for QR codes, you'll see that they are fairly widely used.
I would be fascinated to see those statistics, please share them.

Here are stats from Tesco (large UK retailer) http://shkspr.mobi/blog/2012/10/no-one-scans-qr-codes-apart-...
Finally, some QR stats from the back of a train ticket. http://shkspr.mobi/blog/2012/12/no-one-scans-qr-codes-apart-...
So, in the UK at least, well designed QR codes get a significant response from "normal" people.
A salt package however... Maybe you're in a restaurant, do you pull out your phone? Do you hide away the salt package just so you can read the QR code later? This isn't even described, so why do you want to read it?
We already have a ubiquitous machine-readable way of identifying things, barcodes. Just because you own a barcode scanner doesn't mean you go around scanning the multitude of barcodes on your stuff. In fact, we get kind of blind to the number of barcodes on everything because they are used on everything and given without context.
If QR codes are overused on everything, maybe leading to things as mundane as an infosheet on salt (oh, this is high in sodium, who knew?), or forgotten broken links, they're just going to be ignored except when given appropriate context.
Are "normal" people really interested in getting detailed information documenting the unique ID of the salt package they purchased?
Tesco is huge in the UK but let's be very conservative and estimate that they have 10 million customers a month (in reality I expect they have more customers than that in a day) apparently 6000 of those are engaged enough with QR codes to use them which is 0.06%. That's not a very impressive statistic from where I'm sitting.
