I noticed they were starting to get pressure to cut down on these things about a month ago. VDB'd from a connection for 3 hours, and on an afterthought I asked the RCC if they could print me a breakfast/lunch voucher. They did some calculating of the delay first, then remembered that I would have to ask UX at IAD D service desk about it -- they couldn't handle it. D service desk also did some careful figuring of the delay amount, and eventually issued the coupon -- $5.
