It would probably be worth installing an air conditioner or fan for your employee, since your neighbors do not even guess to open the door. Your guy is a bit of a dork, also a whisperer who, when asked to speak louder, gets angry. I'm sorry that I can't hear you when the coffee grinder is working, and the coffee drinkers are pleased to place an order. I think if you put at least a fan on a person in this heat, he will stop whispering, but he will be able to work normally. And visitors don't really get scented when it's not 10 degrees outside.
