It's been lovely, but I must scream now

Like I said, we're in the middle of implementing a brand new computer system. This morning one of our users was asking about a common everyday work process that he has to do, and the on-site support person said this to him:

"I don't know, we never thought of that."

Excuse me, but you've spent six years and mucho dinero (think really big number followed by lots of zeroes) designing this system and YOU DIDN'T THINK OF THAT?!?!?!?!
