Pros: Dollar in Jackson no longer staffs their night shift.
I arrived at 9:25pm for an agreed upon 10:00pm pickup and no one was at the counter or anywhere else in affiliation with Dollar. The Hertz rep (who a future a Dollar phone rep would tell me to go see) told me that the Dollar rep had left at 3:45pm and that there hadn't been a night shift Dollar person lately. No one rented me a car and I had to pay 3x as much with a different company. I'll never use Dollar again.
Cons: I didn't like... my reservation not being honored and having to play over $100 more for a less than two day reservation to a different company for a last second rental because the local Dollar office failed to hire anyone to work for night shifts.
