(Re)setting up online banking for HSBC on a mobile phone. I remember it being bad. I had evidently repressed the worst parts of this process (and there assuredly aren't any better parts). Many instructions written in a language that looks like it's English, but isn't even a close cousin. Ended up talking to a robot that seems to run on a ZX80, enunciating my requests carefully, and we seemed to be getting on fine, till I'd run up a big phone bill and she declared, perfunctorily (and I suspect accurately), that THIS BRANCH IS NOW CLOSED. I salute their enthusiasm for branch closures, they're not closing the virtual ones.
Of course, any challenge will how have resulted in the complete lockdown our main account, any subsidiary accounts, credit cards, and any and all access to any money we might have. Ah, had we only been Russian oligarchs or Colombian coke merchants, I'm sure we'd be good at this point.
