Can be fun though...
Cycling through Fareham and there is one of the ubiquitous "Cyclists Dismount" signs It is actually on a road, so no break or cycle track.
PCSO stops me and points to sign.Then asks me what it is.
Me " I believe that is a Sign 966"
PCSO Bemused look... "It says Cyclists Dismount and you didn't"
Me "No it advises Cyclists to dismount. Blue background is advisory. There is no traffic, pedestrians or obstruction therefore there is no need to dismount"
PCSO "It means you have to get off and walk"
Me " No it doesn't, however if you are in your official role asking me to do so then that is different"
PCSO " You need to walk through here, or you will get a ticket"
Me "Where can I remount then?"
PCSO "What do you mean"
Me "Well you have told me to dismount, or you will give me a ticket, I will need you to tell me when you will allow me to remount"
PCSO "Are you being funny?"
Me "No just asking you to clarify your instructions"
At which point he was joined by a real Police Officer who took my side and I disappeared happily.
Occasionally see the PCSO around and he still gives me funny looks.
