I've started to develop a small routine. I'll admit to having my fair share of late nights at Posner Hall; study groups, groupwork, corporate presentations, the odd guest speaker are all reasons for treading the hallowed halls of this establishment. The food stop in the building - the eXchange - isn't that great, and it tends to close very early. What does a student do? Order pizza? Possibly. Go off-campus? No - I'm not relying on the shuttles. Scavenge for all I'm worth? Bingo!
Every lunch session (12.30 - 1.20) and evening session (5:30 - 6:20) has an event that is catered - a club event or a corporate presentation usually. It's very rare that there isn't something on. Normally, there is more food than attendees - any remaining gets "donated" to the Master's Lounge where the students, ever greedy bunch we are, all pounce.
There is almost always a reception after the evening presentation too where appetizers and snack-type food is served, and again, very rare that it's all eaten. So I've found myself noting the clock at about 7pm and then wander down to the Lounge where I just wait until the leftovers come by - then I have dinner for the night.
I can't say it's an ideal situation; I am wheat intolerant and it's rare that there is something offered that doesn't contain wheat. But when you're hungry and cheap, like I am - well, I'll deal with the headache that comes after eating wheat. It's free after all.
