There's a level in hell reserved for:

• Marketing people who sell products that don't exist and then wonder why the ship date they promised is missed.
• Marketing people who leave at 11am on Friday while the development team is stuck in the office until 8pm trying to meet a deadline.
• PHBs that drop $2000 on a brand-new laptop for a marketing person two weeks before his first day while making developers wait six months and then spend money out of their own pockets (to be reimbursed at the company's leisure) to get reasonably-performing workstations.

Of course I'm one of the people in here on a Friday afternoon while all of the marketing and sales types are enjoying their early weekends. They think they're entitled to a "break" after having to "work" long hours for a few days figuring out how they're going to make our lives (more) miserable -- promising the impossible, mostly.
