If the computers didn’t work, it would be incredibly painful in Germany because most pharmacies don’t regularly stock most prescription drugs. They’re often ordered from central warehouses on demand - i.e. if you walk in with a prescription for Xanax in the morning, you’ll typically need to come back in the afternoon to pick it up.
That ordering process is entirely digital. If you suddenly switched to paper forms, phone calls, and faxes, it’d be a nightmare.
