You and a business partner have scheduled a conference call with an important new client. The client is on the other end of the line and ready to start the call. Your partner (the one who is the 'expert' and lead for this call) is late by 10 minutes and the client is getting frustrated. Would you:
Explain the situation to the client and ask them to wait another 5 minutes; in the meantime, you give the client a bit of background on the process leading up to what you are about to discuss
Apologize and suggest you reschedule the call
Jump right in and kick off the meeting agenda on your own
