Yesterday I wanted to pay the amount of 24.95 in Migros Gossau SG (M) with a 20 Fr. receipt and a 5 Fränkler. (I didn't have any more cash with me and didn't want to pay by card)
But this unfriendly cashier said she would not accept a receipt. Did I not have any money to pay? I should save these receipts. Hello, it's none of their business what I pay when, why and how. After all, I'm paying, right?

Is it really the case that you can't pay with these vouchers in the smaller branches?
Incidentally, this is not the first time this has happened in this store.

I will go to another store for my future small purchases.
