They have to do it on front of you actually.
But that is not the point. I am not the only one that has to pay that tax, so everyone else is in the same boat regarding the purcharse of floppy disks. All because a comitee of provincial politicians can't be bothered to accept electronic payment of this particular tax. Every other tax can be paid with online banking.
So one of the reasons the purchase of outdated floppy disks keeps going, at least in Argentina, is because of a comitee of politicians. That was the intent of my original post.
