Obnoxious behaviour

On Sunday afternoon I was in Causeway hide. Another visitor joined in asking about sightings and sharing knowledge. I pointed out the water rail that others had previously shown me. Then after a few minutes another man snapped at us in an aggressive abusive manner to shut our gobs he'd come for some peace. WE were rudely dismissed as 'tourists' and other derogatory terms. I live within 2 miles of the reserve by the way. When challenged by the gentleman I'd been talking to he leapt up with fists clenched and I and a third person were obliged to step in to prevent him assaulting the visitor. As a result several of us left the hide shaken and angry at our afternoon being spoiled by this hot-headed intolerant idiot. It won't put me off visiting my local reserve but it may have done for others. Certainly when I see him again I will be tempted to curtail my visit for fear of his violent response. I did check as I left and can confirm that the hide doesn't bear his name so I assume he's a visitor like the rest of us.
