As an ETSU alum and an J.C. resident who has been to Hooters exactly once, ETSU's Tammy is way out of bounds. I worked in a night club as a bartender (serving liquor when it wasn't yet legal for sale in J.C.) while attending ETSU (Crow's Nest) and it didn't disqualify me from being on the Chess Team, etc. Tammy sounds like she's straining at a nat while swallowing camels.
You were working in an illegal establishment. Kimberly was not. There is nothing in the policy, as stated that applies specifically to this situation, or any of the other scenarios I posted upthread.
