Guest, some bloke:Call me weird if you like but I find it important to ask before attaching clamps to a pub's furniture.
Pub prop weclamps are made from soft rubber. The only part that's not is the actual clamp screw, which never comes into contact with any part of the table.
Re makeovers :the silliest I've seen was a local pub with nearly two centuries of character and patina which was completely gutted and refurnished. The new bar, tables, walls and furnishings were then comprehensively artificially distressed to try and make them look "old"! WTF?
