Oh my god FUCK OFF, KAREN. That first paragraph is entirely a product of a situation you - and you alone - imagined, based your own self-indulgent righteousness and prejudice. If the bank has bullshit processes, even the most egregious simpleton would see that by throwing a tantrum at the working class labourer who is as bound by them as you are, all you’re doing is succeeding at making their life worse while utterly failing to address the systemic issue causing the problem. You want to write a letter to their boss, complaining that the worker was hesitant to address an unusual query, you UTTER FUCKING NARK? Get a sense of perspective. You soulless husk.
It’s amazing how stuff that was simple even twenty years ago is so unusual now. I’m in the UK and we simply do not have cheques any more, for example. About ten years ago I had to pay a supplier in the US by cheque and I actually had to go to my bank and get them to print one for me - the staff member who helped me said they’d worked there two years and it was the first cheque he’d had to produce. When I was a kid people paid with cheque constantly, everyone had a chequebook, though I’ve got to say I’m glad to see the back of them. If guess that withdrawing specific denominations of cash is the same. If I just wanted to withdraw an amount of money, I’d use my nearest cash machine, but to specifically ask for this quantity of that denomination is, presumably, a bit left field.
