Oh I remember service 100 now. Thats the only other one we ever use, like I never understood service 80 for example.
I've never had to use service 100 and never want to, its only used in my store in a situation where the police would be called. Like ages ago when I was getting supervision training at night all these 15-16 year olds got in a huge fight in our store, so my boss screams "SERVICE 100 TO THE FRONT OF THE STORE!" into the microphone, then turns to me and says "THAT is when you use a service 100".
Interesting story, I know.
