Hours of operation at AMPS

I have been a few times in the middle of the night between 3 and 4am a few years ago. I wasn't drunk, just happened to be out, drove by, sign said 24 hours, and so got the urge the stop. I stopped doing it because when the girl would come in the room, it was very obvious that she was just woken up to come service me, and was still half asleep. It just made me feel bad that I walked up, rang the bell, and disturbed the sleep of a few of them I'm sure. Then one would have to actually get up do the whole deal with me. Since then I started going during daytime hours, just to feel better about myself.
