>>2719627Another one I thought of.
A girl injures her back and gets recommended a specialized spa and masseuse help with her pain. The masseuse has her get naked for her treatment as a mistake in the process could just make the problem worse. After her massage, he has her go to the sauna area to help heat up her body for more treatment. She can't get dressed yet, there's still more treatment to do and it's normal to be naked in a sauna. What he forgot to mention is that the path to the sauna goes by the lobby of the spa, which has a glass entryway that shows everything to the street. Maybe the saunas are all occupied, so the specialist has her wait in the open lobby so that the massage room can be used by the next patient. Maybe the spa is actually in a mall and they need to go out to another area to get to the sauna. Maybe like the idea above, that sauna is closed for a lunch break, so the specialist has her wait with them out in the open until it's open again. Maybe like the other idea above, the usual sauna is being worked on, so they have to go to a completely different building.
