Be more agile

I got there 40 minutes before the scheduled time for pick up of the car, and i went straight to the counter because there was no line. They told me it was too soon, to come back 10mins before. So I went to a walk, and i got there like they said, 10min before... and then, I had to wait almost 1h because it were ther a line already and i had 5 persons ahead... so i think they should have taken care of my rental when I got there, even if I could only got the car at the scheduled time, at least the contract and the payment was already made.
