Whenever I get a meeting I don't understand why I was invited to, I just ask whoever invited me, or my boss if customer did, what my purpose is in the meeting.

Almost always I can avoid the full meeting with the understanding that they can call me in if they need my expertise. When that happens it's typically just a couple of questions and I can go back.

Sure some weeks can get a bit busy with meetings if we have a lot of projects going on, but I'm almost never in a meeting where I feel I'm wasting time.
