To: Mark Hopkins<[email protected]> From: George Wallace<[email protected]> Subject: March 10 Installation Date: March 1 Dear Mr. Hopkins, As we discussed earlier, I know how important it is for an assembly line to have a power source it can trust. I am sure you will find that our solar backup system is as reliable as conventional backup batteries, in addition to being more cost-effective and requiring very little maintenance. Since we will install the system outside work hours, it will not affect your schedule or cause inconvenience for your workers. If you have any questions before the installation on Saturday, do not hesitate to ask questions. Otherwise, I will see you then. Yours sincerely, George Wallace Sales Director To: George Wallace<[email protected]> From: Mark Hopkins<[email protected]> Date: March 2 Dear Mr. Wallace, Thank you for your e-mail. I regret to say that we have to postpone the installation of the solar backup system. When I met you last week, I totally forgot we have an annual safety inspection by the Wellington City Fire Department on the same day we are planning to install the solar backup system. Id like to install the system on March 15 instead. I apologize for the inconvenience this may cause. Please let me know whether the date is convenient for you. Thank you. Mark Hopkins Floor Manager Micro Goods Company
