Local Pub Wars ?

Going past the Millstone the last week or so I have seen the board outside advertising Greek nights, Italian nights and Spanish nights.

50 yds away on council land now sits a board from The Red Lion advertising a charity night.
The Red Lion is quarter a mile away.
I think cheeky monkeys.

Does this now mean that the post where the road splits between Hawarden Rd and Chester Rd can be used by The Millstone and Penyffordd British Legion to advertise events?
