“David, first of all thank you for your patience with me.  I do understand how difficult this has been and you have now been dealing with the suppliers and customers, with frustration on all sides due to Covid19.  I am very happy with the quality of your products and have been happy to have them again in this second project.  I respect your workmanship and interest in providing the best service to your customers which is why I went with you in the first place.”
