I think our house was the reason for implementing no-frills rules back in the 80s.
In 1986 (or was it 87?), at prefs, we served shrimp cocktails (in the appropriate crystal, of course) and mini-cheesecakes to the rushees.
It was THE TALK of rush...or more like, the SCANDAL! lol!
The next year, Panhellenic started implementing rules on what can/can't be served.
Ahh...if only rush was how it was back in the 80s.... you younguns have NO idea on what you missed out on!
And of course, being at an SEC school - the elite of the elite!
(just thought I'd throw THAT in!)
