I love this story of the interchageable accountant.
Peter wanted a new accountant. He spent ages asking around his local area and getting positive testimonials.Unfortunately, the day he went for his appointment he was running late and inadvertently walked into the accountants next door to the ones he was supposed to be visiting.
Peter says he has since been really happy with the service they provide and wouldn't change them - even though it did eventually become apparent that they weren't the firm he intended to approach.
