Well, the cart deposit in Germany is a 1 EUR or 50 Cent coin, or every piece of metal or plastic that matches the size of those. So no big deal, but people do now at least bother to bring back the cart in line. Smaller baskets are free.
Supermarkets here have neither a packing service at the cashier, nor do they have helping hands. I recall that Walmart or Toom tried to establish the packing service years ago, but this didn't suceed: most women liked to pack their sacs themselves, claiming the packers "would do it a stupid way" ...
Hey, we are use to fuel our cars ourselves for decades (I recently read that there's only like 2 States in the US where this is usual, all others, including the ones I've been to, have fuel service; there was a third one where they wanted to abandon the service and it there was a public outrage ...?).
What we have is the online order service you describe - order online and fetch everything packed later. This seems to be a good idea, but I have not yet tried it. The extra cost for this is only 2 EUR. Or you pay - depending on the value - between 0 and max 5,90 EUR and they deliver your order to your front door.
There was a big silly hoopla over oregon state where it's illegal for folks to fuel their cars talking about making it legal, you have it backwards though. Only two states you can't fuel your own. For the other 96% of america we're totally baffled why that's a task for someone else and do it ourselves
I've been driving for decades and I've never had anyone pump my gas for me.
AH though bagging of groceries. I'd never done it before I went to a bag it yourself market nearby and wow I was like..wait I what? ROFL boy was I slow! I'm sure if it was a normal thing it wouldn't have been so stressful though
I didn't realize that was not done in Germany!
I won't say never, but I can't imagine a scenario where I'd put even a penny into pushing a cart around a store to buy their goods. I'd turn around and walk out first. It's just a complete cultural wall for me on that one!
