PLUG YOUR NOSE, IT STINKS LIKE SEWER AND A GAS LEAK.
Also, people, have your window down and your validated ticket in your hand ready to hand off to the parking attendant-- this will make things move along A LOT QUICKER.
Another important point, if you forget to have your ticket validated.... they MAKE you either pay or go back in and get it validated. One time it was 5 mins before the parking attendant was off and he MADE ME wait for him to close up so the arm would be up or go back and have my ticket validated. I was steaming!! I sat and waited. I can be cheap sometimes, but it was principle at this point.
