The coins are useless. It's a people problem not a mechanical one. You can unlock the cart with the tip of the key like this https://image.made-in-china.com/202f0j00GpWUwrYJnBoN/Sn-Euro... (standard european).

And I frequently do because I HATE german supermarkets anyway!

What's wrong with German supermarkets? Coming from the UK, I generally prefer them.

The only thing that pisses me off is that Lidl and Aldi don't have baskets. In fact my local Lidl had an absurd short-lived policy that you aren't allowed in the shop unless you get a shopping cart! Thankfully they came to their senses. I just use my shopping bag as a basket.

I consider german food products in general to be tasteless (I am not saying they are low quality but it just does not fit my palate). Lidl / Kaufland is fine for veggies. Rewe good in general and I like Billa+ but that's more premium quality anyway.

Just in general not a fan of german food products.

I agree, I find food in German supermarkets pretty bland, there's just something so generic about it all.

That's very interesting, I love German food

Ever since the pandemic most coin locks are always unlocked - and people keep them that way.
