Another Decorative Number...

"A week ago, Dr A disappeared for almost two days. I got worried sick. He usually calls in to tell me if he is coming to work or not, he also calls me if he knows he will be late to work. But Last week, no calls from Dr A. I tried calling him on the mobile but all I got was that damned automated message of “sorry, the mobile youre calling is either switched off or outside the coverage area, please try again later”. Ughhh….I kept trying but to no avail. The next day I waited abit and still no Dr A. Again his mobile was switched off. By late afternoon, I was ready to go and speak to the security in charge when all of a sudden a yellow faced Dr A appeared."
