I'm not sure I understand: rental inspection as in they look around and make sure you're keeping the place reasonably clean and there is no major damage? Because to be blunt, in that case the agent doesn't give a flying fuck what you or anybody else is doing, and the visit notification is pretty much "please don't be naked."

I'd guess if the agent saw a relatively clean place and looked into a room to see somebody working on a computer and taking a call, she probably just decided to not bother you and to get on with the rest of her day.

I'm just confused because I don't understand what else could or should have happened. Are you supposed to lead the agent on a tour of your bedroom while offering them tea and cookies?

In summary, did the inspection actually "go badly" in that you're being charged for something or whatever? Because it sounds a lot like they saw a clean place and called it quits, which is usually the ideal outcome.
