Yes, this is off topic, but just to clarify an above comment:
Ocassionally a student group will rent a club/lounge/restaurant/etc for Wash U students, either the Loop, CWE, or the Landing.
On the specific Thursday Night even that was mentioned, Wash U Seniors tend to go to the Landing to hang out. It's a weekly Senior night or something. There is no specific club rented out for them, but they all congregate at one or two places.
Either way, the University itself doesn't allocate money for any events like this. If there is ever a reserved event for Wash U students, it is put on a by a student group. It's not like the Chancellor said "free beer on thursday nights downtown, on us!"
Basically, 1% of your tuition goes to the Student Government, which allocates the collective $2 million+ to all the student groups (WILD, a cappella groups, cultural groups, etc). It's all student run, and student-decided, so if you have an issue with any of the events on campus (or off campus), take it up with your future peers
