A+ for the drivers.
C for the people at the entry gate.
Regardless of how slow I come in, whoever is attending gate doesn't open window until AFTER I've scanned card. Thought maybe I needed to make more noise so they knew I was approaching. However, the car with the boom beats went through the same molasses-like person.
Why does this matter? The gate attendant usually tells you where to park. But, if you're tight on time then time is of the essence in catching the next shuttle. Cumbaya!
