Sounds like good service. More rental agencies would do well to look at this example.
I've never rented at PHL airport, but I did rent at PHL near 30th Street Station once. The service was decent (albeit a bit slow) but not anything like what you've posted. Looks like the airport branch has their act together. Hope that branch manager gets promoted upwards.
FWIW, professional dress (suit and tie) is standard at Enterprise nationwide.
