Phone follow up

I have to add that I am not at all opposed to helping out. If our admin ask me to grab the phone for a few minutes, no problem. It is when other architects ask me to do it instead of doing it themselves - example: a meeting was moved from one conference room to the other and a male architect goes to tell the people in the room to move rooms and then asks me to go and get the coffee and move it rooms. Now that male architect was already in that room, why couldn't they just grab it instead of asking me?
