Late evenings are cool, just not too late, weekdays would work just fine. If you cruise in too late the associate is distracted trying to close down and focused on trying to get all the crap done thats needs to happen before he can walk out the door. On a busy day it takes about 3 hours of almost complete focus to get out on time(an hour after we run the customers out). What part of DC are you in? One of the guys in my dept came from the Fairfax store and still has contacts up there.
