I worked for ERAC. What does happen to a walk in is that they are quoted 910 rates. However, the customer is told the only thing they have is a full size car. I have been in the airport waiting in line and overhearing the managers tell the customer that they only have full size cars. I tell the customer to call 800-rentacar from their mobile and not to tell the reservation clerk that they are at the airport and make a reservation for a compact or econo car. They get back in line and get what they want. I even offered a guy a drive to a local branch just so he get the appropriate car. I hate ERAC, however, my company has them as the one we use.
