Buying groceries Germany Aldi's and Lidos was the most stressful part of my time there.
Why?
The swedish system feels superior in my honest opinion. There is a big area afterword divided by a Y bar so 2 people can be served simultaneous. The 2 top Y boms are electrically controlled by the cashier so groceries goes to either left or right side.

So when one is finshed, that person can pack everything as he/she wants without hurry while the other persons groceries are served simultaneous by the cashier and that persons stuff goes to the other side.
Useally you could pack your stuff without hurry while the 2nd person is served. But if both side temporary is not finish because two big shopper both Y boms could be closed so 3 people could be served simultiously. Two could pack and the 3rds groceries could still be handeled by the cashier.
And not to forgett, everyone in sweden (almost) payes with card which speeds stuff up alot. You pay while the cashier scaning the groceries. When finished you just press "ok".
