Oh my god.
First, she doesn't understand anything about food prices. She genuinely can't look past "cheaper is better", which ignores all the workers behind that price tag. I've mentioned before that I have friends in agriculture; this is a big problem in a lot of countries (here we kind of venerate the noble peasant as a cultural symbol, the traditional farmer's hat is a big part of the national dress etc...but we stick our fingers in our ears when it comes to paying them a fair wage). It's gross that an "influencer" shows so little interest.
Second, yes to all who said that supermarkets are rebranding value food. Growing up in South Africa, the value range in the supermarket was literally called "No Name Brand". Buying that shit is humiliating - I would much rather go to Lidl and buy a normal-looking Harvest Moon tin, you know?
Third, why does she think poor people should survive on the cheapest, nastiest muck? Shopping on a budget should never mean filling your basket with value spaghetti hoops (or any spaghetti hoops for that matter. They are an abomination!). It should be about stretching ingredients and avoiding waste. It should also be about exploring which value stuff is fine, and which is not.
For example, those sausages? No. They should not be recommended to man or beast. Some things - flour, frozen fruit and veg, yogurt etc - are perfectly fine cheap. Buy cheap plain yogurt and mix with fruit, rather than Muller Corners or whatever (this may seem obvious, but it's clear from a lot of online commentary that there are people who benefit from this type of advice). She should be comparing loose veg prices with packaged veg, looking at BOGOFs and 2x3s to see if they're really worthwhile, etc. Instead she just thinks poor = cheapest shit around.
Finally, my Lidl is 3km away, a 40-minute walk (no good bus connections). I go every couple of weeks, and I actually have a job. Give it a go, Jack. The fresh air will be good for you!
ETA: She is convinced that Brexit will make her relevant again. Remember peeky_mink predicting food riots? She can't wait for it, the selfish twat.
