Mythical creature vs 'Real-World Sighting'? I try to never underestimate the potential for someone to do something really stupid and I'm sure there are some egregious examples out there where a DB was set up and run such that outrageous charges resulted; but has anyone seen a situation in real life anywhere close to this kind of example? Even if there was a instance where a poorly designed and implemented data set caused a $40K charge for a single day; I wonder how long it would take for the bean counters to notice and take action?
