Returns are easy
What is less easy is the process. Unlike most places where it’s straightforward, in Aldi/Lidl you turn up at the checkout with your return. They check the receipt and see it’s fine. Then you discover that the checkout staff aren’t trusted, as the manager is required for special key to allow them to do the return. They’re usually miles away so as ALL the customers in the queue get frustrated with you returning something and taking ages, you wait patiently getting increasingly annoyed as it’s such a waste of time.
So they didn’t quibble it, but it’s slow if the manager isn’t standing next to them
