They won't come and say it to your face in a billion years Tracey! Worse still, they'll shake your hand and be oh-so-hopeful that business is going well for you, only to turn the corner from you and tell someone your fish and chips are the worst on the planet. They won't have tried your fish and chips but that won't matter.
Mrs Scunner is like an armoured truck to these people, far better than I ever was. "While they're talking about you they're leaving someone else alone" she'd say. Personally I'd prefer they were talking about someone else and leaving me alone, but life's not like that
Anyway, forget it, I've heard the chips are good, the charity's benefiting from your efforts, and some people over there won't like that
