I am a shop owner in a very small town. The pub in the town is on the corner of a very busy crossroads, controlled by traffic lights and pedestrian crossing. It has two exits/entrances to the car park, one opposite my shop and others on one road and one round the corner opposite a mechanics. a bus top and residential. The landlord of the pub has closed off the entrance/exit on my side to put tables across - he has used planters and a black board explaining to use the other entrance, which is also closed until pub opening times. It is causing reduced trade, confusion for traffic and pedestrians alike. He seems to have just taken it upon himself to do this, much to the dismay and concern of local businesses and residents alike.
Sorry, the brewery who employ the landlord own the land.
