In my town CG's are not used at lights. That's what the walk button's for.
Our crossing guard is this short, stout girl that was in a class ahead of me.... Though she was in special programs so I dunno what grade she was in ultimately, but she was right around my grade because she was in Home-Ec classes when i had to take them.
Anyway, she guards the kids at a pretty hairy intersection as there's actually 5 roads converging. Very strange intersection, but that's Western PA traffic patterns for you. Nothing's laid out in a fashion that is convenient.
The girl does a good job, but the woman before her was a trip.
She was "large", we shall say, and wore stretch pants EVERY day. She had what seemed like 3 pair. One black, one white stained, and one "flesh" colored.
Now, as you can fathom, the flesh colored were the worst of the bunch, and gave the illusion that she had absolutely NO pants on, and was an enigma of nature in not having a butt, nor any orafice(s) anywhere. Creepy? Indeed. The fact she looked like curdled milk down there didn't help.
And to top it off, cars going full steam would have to SCREECH to a halt as she would step right out in front of them to stop them. This cross isn't near the school. it's a couple blocks away on the main drag in town, but enough kids cross here that the guard's been deemed necessary.
Like I said, new girl is good at the job, old guard was a wreck herself, much less capable of preventing one.
