Anecdote: I went to a charismatic non-denominational new wave evangelical thing in Maui, for reasons I will not explain, call it amusement. I paid particular attention to the pastor before and after the collection plate, and it amused me so much that I went back to confirm what I had first seen: that every ounce of his charisma (and boy was he loaded in that dept.) drained from his Animus as soon as the collection plate was full. He would disappear into the background to suffer the remaining service until which time he could count his winnings.
