I can top that. I sit right next to a Very Important Executive, who has an office with a door that closes (I, of course, as a very unimportant peon, sit in a noisy open office next to QA people who are testing voice-activated devices all day). However, VIE’s office gets hot if he closes the door, so he leaves it open all day. He also doesn’t like to use his telephone headset, so he leaves his phone on speaker. All day. Every day. And the thing is, he’s actually a really nice guy - it’s like it never occurs to him what an inconsiderate officemate he’s being to everybody around him.
