Enough people have given up cash that it seems some widespread blindness/out-of-touchness on the assault on cash. This thread is collect scenarios of cash payers being hit with fees and other disadvantages as the war on cash moves ahead.

• Internet service: the only way to get an Internet subscription that is paid directly in cash is to buy a prepaid GSM then buy top-ups from press shops, and use the phone credit to buy Internet bundles that cost around €15 for 4gb. Subscribing to a proper ISP gets the lowest price but requires paying by bank transfer. And to do that, you have to pay a fee to a 3rd-party service that takes cash and makes a transfer.
• GSM service: same problem as Internet svc. Prepaid costs more. Postpaid incurrs fees by 3rd parties.
• rail transport: online tickets are the cheapest and none of the payment methods are cash-compatible. E.g. PaySafe cards are not accepted. OTC service accepts cash but has extortionate fees. E.g. a fee of €12 added to a ticket that costs €10. Or you can be a victim of dynamic pricing, and pay cash after boarding, when prices are the highest.
• buses (long-haul): Dynamic pricing fucks over cash payers. You can pay online but only using a bank-dependant variety of payment instruments. You can pay cash to the driver, but only just before departure, when the price is 4× higher than the starting price.
• buses (public transport): some bus companies outright give no cash option. Some charge 50¢ more to cash payers.
• basic utilities: cash refused. Must use a 3rd party transfer service to pay cash, for a fee.

Any other situations where paying cash has a penalty?
