My office in PR uses Securitas workers for security, and they are among the most polite, well-trained, and cordial security guards I've ever dealt with!

Generally they are very good, but there is one Securitas rent-a-cop working for Boeing headquarters in Chicago who is a perfect example of what can be wrong with r-a-c. He came running out of the building trying to make my daughter stop taking pictures of it from the sidewalk. We just laughed and left.
