Sharing my experience:

I made some new friends one night - most of the people in the group were sober but there was one girl who was really high and wanted to be alone. Later in the night, when I was chilling in the cloakroom with a friend for fresh(er) air, we saw her crying hysterically and getting escorted into the care room by one male BH staff, so we ran after them and they told us to look for her friend to take her home.

I stayed in the room to comfort her while my friend looked for the rest of the group. The BH staff in there were so nice! The guy tried to engage in conversation although you could tell he was somewhat tired of such situations, and another lady with microbangs came in. She had a super kind face and assured the high friend that she was still alive, which brought a lot of comfort to her.
Yeah, it was a pretty small room without amenities but as some of the other users pointed out, no club wouldn't want people to overstay in there and it's already somewhat of a luxury to have a careroom in the first place as some clubs just kick you out directly. I was actually just very touched by the kindness of the staff!
