At about 3.5 - 4 minutes per car in the express lane for newer cars, who can complain? Well, many I'm sure but not me. The wait-times are available on the ADEQ web site and though it can change between the time you might check at home and the time you get there, you can still largely avoid long lines (and this station has lesser wait times than many of the others anyway. Service was fast and just fine. Spare me effusive over-friendliness - just get me tested and out of here - and they did. No complaints. Very efficient and not unfriendly. My compliments.
