If they pay by transfer they can charge back, the bank might cancel for some credit reasons, might flag it as they want to verify first why it was made, and so on. Cash is problem free if you live in a low crime area.

I do myself all higher priced purchases in cash, even go to the bank and withdraw the money to go to the shop next door. For the same reason I use a VPN. My provider and my bank have no right know what I do or not do.

None of that can happen with instant bank transfers. If the bank says it's cleared then it's cleared and it cannot be charged bank anymore.

Charge backs don't really exist in Europe. The bar to clear for your bank to reverse a payment is extremely high.
