You are roll calling in front of a party, and you notice a PNM is running to you from down the block, you ask a bouncer to ask what her PNM number is (this is all happening right at the 1 minute knock is approaching), what do you do?
What is have the bouncer tell you her number, mark her as present, turn the list in, and put her in number order in line
Or... if you have already turned the list in, place her at the end of the line, and make sure you tell the chapter member inside she arrived (so they can edit the no show form)
