A team mate of mine recently posted about lying to his event attendees.

I just want to go on the record for MY North Eastern USA Event Attendees that most of the MSDN Events guys, and certainly those on the EAST COAST - don't indulge in this practice.

"I don't know", and "I can't say" are honest ways not to jeopardize ones job.  

For the record........

Lying to customers = BAD, being truthful = GOOD !
