I’m very much up for being employed to travel the country and each Wetherspoon’s to collect and correct the merchant data…
I’m only asking for travel, and costs for as many cans of Lo-Res and pints of Punk as required for the task. 
Seriously though linking to the Wetherspoon logo should work; I’ve submitted updates with the link to a companies website when they haven’t used Twitter to great success in the past.
