You're risking your job setting up a date at the workplace. In my opinion nothing ends well when a guy decides to dip his pen in company ink.
Rather than worrying about workplace c0ckblockers, I would be looking into my company's policy on dating within the workplace. Most companies state in writing that you must disclose if you're romantically involved with someone in the office.
In this economy, I'll be dammed if I'm gonna allow a girl to endanger my source of income.
