‘Kids these days! [A reader] writes, “My lectures about financial responsibility appear to have failed: yesterday [my teenaged daughter] charged $23,148,855,308,184,500.00 at the drug store.” You would think Visa would have caught the error and addressed it, if you were high. What Visa actually did was slap a $20 “negative balance” fee on it, of course.’

And this, from the comments to the post:

“Maybe the bank mistakenly converted the charge into Zimbabwe dollars?”
