HR Wench: 3rd Party Recruiters: Listen Up

I get annoyed when recruiters start letters with demands for information. People who contact me should start with what they are offering, not a petulant demand for information that was contained the resume I know they've read. I naively assumed that these recruiters (or rather, the agency, since I've received the same e-mail from multiple people at one firm) simply failed business etiquette 101, but it turns out I should be grateful, since the owners of multi-employee recruiting firms have decided that the location, nature, and salary of a position is classified information that a potential recruit does not need to be told.
