When my parents told me they were “going back to cash”, I thought here we go: more boomers romanticising the Dark Ages. But then they explained it was all to try and dodge the transaction fees that were dipping into their hard-earned retirement fund every time they tapped their card. And, though I mocked them for being conspiracy theorists, I couldn’t help but wonder (cue the Sex and The City theme), what were these fees really costing me?
