On the other hand, in the UK, Tesco, Waitrose, and Sainsbury’s are all at least as good as their German equivalents; and (beyond the EU) even the worst EU supermarket was better than almost every supermarket I saw in the USA.
I never paid attention to the price of groceries when shopping in Germany because growing up poor I always had the attitude not to be stingy with food and only buy what appealed the most. Coming to France I had to pay attention and actually look at the label because I might pick stuff that I simply couldn't afford. Doing this in Germany I might end up paying for regular groceries 250,-- (avg feeding a family), while in France I might pay 800 or more if I didn't pay attention. The first few times had to actually return once the cashier presented my bill.
