I may end up trying Hertz, which has an office near me, but their rates aren't as good, unless I can get them to match the discount Enterprise has given me.
But none of that is the point here. The point is that I dropped off my last car from the Davis office today, and Erin, who will be moving to the other Somerville office, basically bent over backwards to try to keep me as a customer. She's willing to pick me up early, give me free overnights, drive me places in her personal car, in order to keep me. This makes me feel a) appreciated and b) willing to put up with some inconvenience in order to stick with them.
Yes, customer service works.
