People in their lounging robes

I love Le Nordik, the scandinavian spa just 20 minutes from Ottawa. It is amazing, and reasonably priced. Much cheaper than therapy, and you come away feeling refreshed and rejuvenated without having to talk to anyone. In fact, they encourage silence there. I loved everything about the place, except for one thing: people wearing lounging robes, robe de chambres, morning dresses, housecoats, bathrobes, wrappers, yukatas -- whatever you happen to call them.
I was trying to explore what I dislike about them, and I think it may all come back to the intimacy problem. I feel strangers are getting too intimate with me when they are wearing those things. On the other hand, I love people in their bathing suits. No problem there. I think I might be ok with them naked, too, if it were a nudist scandinavian spa. But, there was something about seeing that silver-haired devil in the bar area in his red terry cloth robe that freaked me out. Maybe I need to discuss this with my therapist.
