There is a concept known as HSP (Highly Sensitive Person) which is more easily explained at the link of the psychologist who developed the concept,

The manager you mention could very well belong to this group. I belong to this group. In fact, I have a formal diagnosis of belonging to this group (too long a story). In my case, the effects are primarily physiological. I.e., I don't like amplifiers cranked up to an insane dB level, I don't like flashing lights, etc.
Per the link, about 15-20% of people in general belong to this group. But so do their pets. It therefore would appear to be genetic. Perhaps Mother Nature's 20% gamble to insure the survival of various species.
I don't know if this means SCs drive away 20% of their potential customers or not. I'm not sure those belonging to this group would ever feel comfortable in such an environment.
Yet, it would be an interesting experiment for someone to open such a club which caters to such customers. It would require continual subdued lighting within the club, a dB level where it is possible to have a normal conversation, and probably a no smoking policy within the club. And dances which are far more sensual than overtly sexual. Also, a very reserved exterior and interior design to the club. The interior and restrooms at such a club would have to be kept spotless if you wanted repeat business from such customers.
It's also interesting to note 20% of the dancers working in such a club might also belong to this group. Although if the experimental club suggested here existed in reality, it might be much higher than 20%. In fact, you might need about 80% of the people working in such a club to belong to this group, in order for such a club to be successful.
