But there's no excuse for staff getting muddled about their own roles, especially in front of their peers at tender briefings.
At a meeting for those keen to pitch for the Carbon Trust's PR work in July, a former Hill & Knowlton director now at Fleishman-Hillard let herself down somewhat.
When her turn came to ask a question of representatives from the government-backed body, she blurted out the name of H&K as her employer, despite ceasing work there six months earlier.
Realising her mistake, she apologised and stressed she was now happily ensconced at F-H, thus reducing the room - packed with PROs from over 100 separate parties - to 'hysterics', according to one delegate.
Our lady, whose blushes we spare but who will be immediately identified by friends and colleagues, fesses up when called: 'It's a fair cop.'
