I work IT for a network of hospitals and take calls in my cubicle all day. This is a call I just took.
Client: Hi, I was wondering if I could install Remote Desktop on my computer.
Me: PC or Mac?
Client: It's a Mac.
Me: Is it a personal computer, or is it owned by our company?
Client: It's mine.
Me: I'm sorry, we don't provide support for personal computers on this line.
Client: Oh, I don't need help. I just wanted to know if I was allowed.
Me: ...Sure. Go right ahead. You can do whatever you'd like with your computer.
Client: Great! Thanks.
