I hope that Migros has negotiated its contract with SIX, the (arrogant) provider of the card payment solutions, wisely so that SIX has to pay compensation for the loss of sales that Migros suffered today because it was not possible to pay with Mastercard/Visa in the stores! (Not in Migrolino, Coop etc. either, i.e. nowhere where the SIX terminals are; everything worked fine via Aduno terminals, e.g. at the kiosk).

I left my purchase annoyed at the Migros checkout! I'm sure I wasn't the only one ...

You could see from the queues at the checkouts how inefficient and slow shopping is (or isn't) when everyone has to pay with old payment methods.

Migros is not to blame for the failure, SIX is. As a disgruntled Migros customer, it would be satisfying for me to know that SIX is not simply getting away with the damage and annoyance caused.
