Roy is a customer service officer working in a local trading company. He receives dozens of emails daily, ranging from enquiries to complaints. His job is to reply to these emails as best as he could, if not, refer to the necessary departments to follow up.
There was once he received an email on one of the webpages. It wrote:
On <URL> you wrote “prevoius”. Such an error shoud be no tolerated.
Roy clicked on the URL to see what the webpage was about. It was one of those pages introducing the new products. There were easily 1000 words in that page. He found the mentioned spelling mistake in the middle of the fifth paragraph. He quickly informed the webmaster to make the necessary corrections. Then he proceeded to draft a reply to the sender.
What an irony, Roy thought. The sender was quick to point out the spelling mistake in the webpage, but he failed to notice the spelling mistake and grammar mistake in his email that consisted of only 11 words.
