this is just a short note to thank you for your service in both the purchase and the sale of this business over the past 6 months. I will have no hesitation in recommending you to any possible purchaser and vendors, as indeed I have already recommended you to my brother for the sale of his business. I believe you have acted with the best of intentions and integrity at all times and wish you well for the future.
