The button pressed twice reveals a hope that effort can make waiting shorter.

Pressing again does nothing, and almost everybody does it. It comes from a deep expectation that effort and result are connected, which holds in most of life and fails completely in front of a lift or a crossing. What the second press really expresses is discomfort with having no part to play.

Notice where you are adding effort that cannot affect the outcome: refreshing a page, checking a decision that is not yours, rereading a message you have already sent. Naming those as waiting rather than doing frees up more energy than it sounds like it would.
