You're forgetting the important details...Was she hot at least? Did you get a picture?
Only kidding (sort of).
If you weren't cited/arrested/etc., then you have nothing to worry about. It sounds like a routine contact where they were investigating possible prostitution. Once they determined that no crime had been committed, that's it. There is no reason that the officers would contact your employer. Your company policy is not law enforcements business. And quite frankly, we really don't care. After they talked to you, it was on to the next "suspicious" car or whatever the case may have been.
