I love Savory Deviate Delights, and I always keep them on hand for instance runs with my fun-loving guild. One day I took my lvl 70 undead rogue out to the Barrens to acquire more deviate fish, and she still had her costume on. I left myself stealthed in the Crossroads for a few min while I walked away from my PC, and came back to find that I was the subject of a manhunt. Apparently no one targetted me to find out that I really wasn't alliance.
I found this rather amusing, and they dispersed after finding out that I was horde.
