Gate lines and the time before kickoff
The gate line before kickoff is the heaviest use of the day. Units are placed at the back of the line, where people who have just arrived are deciding whether to wait.
A gate line forms over the hour before kickoff. Units at the back of the line are found first, so they are placed there and not at the front.
The units must not sit in the line itself. A unit in the line blocks the people behind it and the people at the gate.
The line is checked before the gates open, and a unit that has been used heavily in the wait is serviced before the crowd arrives.
The lots, the plaza and the walk from the transit stop
The lots fill over the afternoon and the plaza holds the crowd after the match. Units are placed where the walk from the car or the stop is shortest and off the vehicle lanes.
A lot row is served from its end, where the walk from the car is shortest. The units sit clear of the lanes so that a delivery or a tow can pass.
The plaza is where people gather after the match and wait for rides. A unit at the plaza edge catches that crowd without blocking the walk.
The route from the transit stop to the gate is marked, and units are placed on it, so a crowd coming off a train or a bus finds one quickly.
Servicing a venue on a busy day
A venue event is serviced before the gates, at the break and after the crowd leaves. A late or weekend match, or a double event, gets an extra visit.
The first visit makes the units clean and stocked before the gate line. The crew is out of the way before the crowd arrives.
The break visit covers the heaviest use of the middle of the event. It is short and aimed at the units nearest the gates.
The last visit after the crowd leaves clears the day and checks the units for damage. A unit damaged in the crowd is taken out of use until it is repaired.
