Absolutely horrible experience

At PHL: The service staff was great but the organization is absolutely horrible. People were in line for more than 30 minutes. The staff did everything they can but with completely outdated computer systems and archaic booking methods, it was not easy to respond to large crowds. At BOS: though the website said 24 hours open, there wasn't anyone when I dropped the car. No instructions, no guidance, no pointers. At least a courtesy note would have helped. I went all the way to Hertz service side to ask a random contractor if I can leave the car and keys and walk away. Absolutely horrible, especially for weary travelers.
