I saw a great deal on Best Fares for a dollar a day.   It was a promotion to reposition cars.  I knew what the rate was with taxes etc.  When I got to the counter, the rental agent was very pleasant.  When he realized that I was not going to upgrade he became Mr. Hyde.  He told me that my car would probably break down if I used the air conditioning going over the Grapevine.  Maybe I should rent a V6.  No I was sticking to my guns and going with the original rate which is the only reason I rented from Dollar\n\nI wanted to add an additional driver for the trip back to California.  I only needed the extra driver for the last two days.  The additional driver rate was $10.99 per day.  I only needed it for 2 days.  His reply was, you got the car for a dollar a day, what's an extra $10.99.  My answer was $55.00.  He was not happy.  So to add the other driver I have to go to a Dollar rental car site.\n\nI did call the manager on duty and told her what had happened.  I didn't want a better deal, my deal was great.  I just wanted her to know what I went through so that she could communicate this to the agent.  She was profusely apologetic and was planning to let the agent know that this was not acceptable.\n\nWhen you are on a budget, you shouldn't feel better if you can not afford more.
