I rented from Alamo in DEN this past week. I forgot my QuickSilver card at the office but it didn't matter as there were 3 agents and no other customers! I had my contract signed and keys in hand in less than 4 minutes.

The last time I rented in LAS (as this is where Catman's complaint originates) was last year from Hertz. No line, no wait, no problems.
