One might also look at Rayner’s anecdotes about her mother in another way. It’s highlighting the difficulties that anyone with impaired reading ability might encounter when shopping in this self-service age where, for most products, we no longer ask the grocer for what we want.
Poor literacy, English as a second language, learning difficulties, declining mental function or impaired vision can make self-service shopping difficult for many people. If the graphics on food labelling are poorly thought out, people can make mistakes.
Not everyone shops in large supermarkets where product types are grouped together in long aisles. Poorer people may shop in street markets and pound shops where cheaper products can be jumbled together; where what is on offer can be random and fleeting.
Look at this product. The image is taken from the website of a major retailer. What tells you this is dog food unless you are a dog owner and know that Butcher’s is a pet food brand? The only verbal clue is “vet recommended” on a small label which, if you can't read, you can't read. The graphic of a chicken, a salmon and a turkey doesn’t scream dog food.
Taking this off-topic for a minute, to draw on a recent discussion about WASPI pensions and why two DWP publicity campaigns failed to reach the target demographic. The first featured a Monopoly board and the second featured two dogs on a beach. What did a London-based board game about property acquisition and development and two dogs on a beach have to do with a national change to women’s pension age? These campaigns cost millions and yet the majority of women at whom the campaigns were aimed, failed to notice them. Why? Probably because the graphics had nothing to do with the subject.
With that in mind and bringing the discussion back to the two allegations made about Rayner (which may have been simple mistakes), there’s an argument there for making the things we have to deal with - whether it's a tax return, voter registration, a benefit claim, shopping, online systems etc etc much easier to see and understand for everybody.
