The University of California at San Francisco has told medical faculty members that they cannot spend more than $75 in university money on a bottle of wine at a recruitment dinner or other official event, The San Francisco Chronicle reported. A by-the-glass limit of $15 was also set. A spokesman said that most professors understand the need to limit such spending, but that there have been periodic incidents that prompted the new rules. He noted one recently rejected expense voucher for a dinner for six people where half the bill was for wine.
