@zdl First of all, you will note that I did not claim stealing cash doesn't exist. Very specifically I stated that hereabouts the burden of accepting cash payments seems to be lower on businesses than the burden of cashless payments. In fact, for anything below ca. EUR 20, many businesses flat-out refuse cash-free payments. Hence, your claim that cash theft makes handling cash too problematic is not substantiated here.
Cash theft still exists, sure.
