I work at a large multi-national company. The culture there is that if you needed to communicate with someone, no matter if they were in your time-zone or not, you picked up the phone and called.
One evening, after I have gone home for the day, the phone rings. It is my manager, who lives and works in Australia. He is calling me, after hours, at home, to tell me that someone is going to call me, the next week, to talk with me about something. After I hang up, I tell my roommate about the call and say: “I think that an email would have been more practical and a lot less expensive.”
To this day, I have no idea what they (whoever was supposed to call) were going to talk to me about because they never did call.
