First of all, your "letter" is far to articulate for anyone at MSC (and possibly all of their friends, if they have any) to understand. Someone will have to translate it for them, and they'll never go to the trouble. You might have been better off simply saying: "MSC sucks, just like the fucking NCT. You guys can eat shit, I'm outta here!" Now that's something they can understand. It still won't do a bit of good, but at least they'll get your point.
Since you don't have a snowball's chance in hell of ever getting a response to your letter from the boys at MSC, I'll take the liberty of addressing your points. I would hate to think you put in all that time and effort into this letter for nothing.
MSC isn't a "service industry" It isn't McDonalds, it's just a dive strip club in SF. You're attempting to take the high road and equate the porn business with a "respectable" one that regularly deals with the entire public at large, not just a group of weekend pussy seekers. Therefore, the porn industry has developed it's own set of rules and standards, and has been quite comfortable and successful living by them without the encumbrance of wondering if they will ever compare favorably with a "successful management team" in the "service industry." In fact, a striking example of this is the MSC itself, which has been making a mint over the years, but it's rabid lack of regard for customers (and employees, I hear) has been legendary. Just take a walk downstairs to the restrooms anytime and take a big sniff. You'll see what I mean.
You are mistaken in assuming that MSC is attempting to "maximize it's revenue stream." It's simply attempting to protect it's ordinary, regular revenue and profit that it has previously enjoyed until this year, when the practice of charging stage fees to the dancers stopped. Are you now suggesting that the MSC endure consistent, daily loses just because you want to continue to go into some small, dark, smelly booth and hump one of the dancers like before? Are you really serious?
I'm afraid that, no matter how many years you've been going there, the MSC doesn't owe you a damn thing, and it's free to try and make money anyway it can, which is exactly the "business plan" right now. You can write a million letters to MSC, and they'll all end up in the same place. You're only alternative is to find another place, a solution the MSC is perfectly happy with, because as you have so eloquently noted, the MSC doesn't need regulars, just customers, and naive and experienced ones will do just fine.
