There is a very similar situation in Germany. The reason behind this is that you can use older POS systems for tax fraud (I never fully understood the details), which apparently was quite a thing amongst smaller businesses. The tax authorities then demanded a perfect chain of paper records (apparently the paper recipe contains some kind of a reference to earlier transactions). Bizarrely, they actually asked customers to keep these receipts which pretty much no one really did, but it was a public topic for a couple of weeks.
