Diets, Dogs and Dames

Yesterday a regular customer came into the shop accompanied by her lovely Norfolk terrier. We (staff, owner and dog) all had a bit of a chat and then dog and owner went on their way. After she had gone I remarked to one of our staff members that the little dog had put on a bit of weight. We thought this was because the dog was getting a little older and and maybe not quite as active as she had been. Also she had had a recent hair cut which made her look a little 'plumper'. 'Perhaps she needed a week or two on a diet?' - I said.
Little did I know that there were two other female customers in the shop while I was saying this. They had overheard our entire conversation regarding weights and diets, and put two and two together. The Ladies had not heard us referring to the dog, and thought we were talking about them! We hastily explained that we were talking about the previous customers dog, but I am sure they did not believe us. Next time I will keep my mouth firmly shut and my thought to myself.
