I think it's basically a good idea that you can now scan your Cumulus card yourself at a special machine at the checkout in Zurich-Altstetten. But it would be good if you could do this while the cashier is scanning the items. Then I can take care of the card and pay at the end. I would like to look for the money at the end or be busy with the credit card. That's why I hand the Cumulus card to the employee as usual so that she can scan it when she wants. However, there have been a few times when the employee has refused and told me to do it myself. If I have to do more and more myself anyway, I can scan all the items directly, which I think is a shame as there is no longer any contact with the staff.
