To provide a bit of light relief from all that niceness going on on the other thread...
eg I did used to enjoy directing people in the wrong direction entirely when I was a teenager (until someone came round the one way system again later and spotted me and shouted at me!!)
Again when a teenager, we used to have a similar number to our local hairdressers and get about 3 calls a day for them. I did sometimes used to book appointments for people if I was feeling very naughty.
The one I enjoyed the most was this. Walking down Notting Hill Gate and a public phone was ringing. I picked it up and it was someone calling about a motorbike for sale in Loot. I made an appointment for the person to come round and gave them a false name and address.
I was a HORRID teenager but it was fun
