Jack-
Really, you should just pay for all golf and slap down $XXX for a bar tab at the course as people come in to the clubhouse. Have the staff cut it off when it hits your limit.
That way you have receipts for exactly waht you brought in from the sponsor. As long as that happens, you owe zero dollars in taxes.
I won't be drinking, but I'm thankful for any money provided by Jack. Beggars can't be choosers! Sure is a nice gesture by Jack and handicapper and his wife. Thanks again, guys!
