So they spent $60k on snacks. Let's say they could have gotten by with a third that budget. So they're saving $40k now. Not only is that only 0.0002% of their budget (the equivalent of someone who makes $50k a year wasting a dime), it probably cost more than that to put together and present the report. Small problems should be solved with small solutions (such as telling the conference planners that things seem to be costing too much, so they should try to be more budget-conscious: a solution which would take 15 seconds and cost nothing). Solving a wasted dime with a 26 page report is like spending 2 weeks improving the speed of a function by a few milliseconds when the function is only called once.
