This'll be a good story to tell at the bar once all the money comes back. I'm still baffled by how someone thought "let's see what happens if I send $20k here when the system says it shouldn't be possible". Strip a few zeroes from there and I guess it's worth the funny anecdote, but these are serious amounts of money that the author just sent into the black hole of bureaucracy for shits and giggles.
I think if regular people used these transactions more we’d have more errors. But then I suppose the UX would get improved because we’d have millions of transactions instead of thousands.
As it is now people spend a lot of time and so bad UX can still be successful. I probably spent 20 minutes on the treasurydirect site and their purchase/transfer page as opposed to seconds on my consumer-designed bank page.
