Say it with me -

This is my trolley. There are many like it but this one is mine. My troller is my best friend. It is my life. I must master it as I must master my life. Without me, my trolley is useless. Without my trolley I am useless. I must steer my trolley true. I must steer straighter than my enemy, who is trying to get discounted meat quicker than me. I must get it from him before he gets it from me. I will. Before God I swear this creed: my trolley and myself are defenders of my shopping, we are the masters of my enemy, we are the saviours of my life. So be it, until there is no enemy, but peace. Amen.

I'm ashamed to say I don't understand what I'm looking for here.

The cheapest grill you can get.

Be careful, these are so called "Gittertiere" and they like to be in flocks.

Go back into the Lidl, buy a good broom, paddle the trolley home.

Am I the only one?
Step 1:go back to the car
Step 2:grab whatever size coin is equivalent to the token (it's a quarter here)
Step 3: insert into broken cart and put good cart back first
Step 4: put broken cart back at the end

That way it's the next rub's issue.

They don't work for side loaders, but you can get shopping cart keys for your key ring or whatever you use, that you can plug in and then immediately pull out once it is unlocked. Just don't be an ass and bring the cart back of course.
