Man the office

I work in a leasing office and all three ladies have their phones in their hand. The only guy will be manning the office. He has got to hold it down because three people will be either sick or putting in PTO for that day lol I am going on behalf of my 15-year-old daughter who already has strategize and told me where to go and what to do. I have never in all my 53 years done anything like this?
