Yes....I did read you reasons for continuing to use Enterprise and I believe your excuses are bunk and probably self-serving. To what end, I can only guess.

Lets look at your reasoning for continuing to use Enterprise:
1) "Its a short walk....my time is valuable and the initial convience is worth a lot". Doesnt quite hold water. If your time is so valuable, why did you repeatedly waste your time with a company that continually disappointed you? If your time is so valuable, why the effort here?? It takes considerable time to construct and maintain a website. Not to mention you are posting in the middle of the day. Time doesnt seem to be a true concern with you.
2) The staff at the rental office are young, try hard, and seem genuinely concerned. Nice try, but again that is pure crap. There is this local grocery store just 10 blocks away from me. The staff there is the best. They always went out of their way for me. However, they dont always carry alot of the items I want and many times they run out of what I need. I stopped shopping there. I didnt continue to go there time and time again complaining loudly about customer satisfaction. I certainly didnt invest time and money into a website because they continually disappointed me. I just drive ten minutes further away to a larger store where they have want I want, when I want it. Try again Admin, that doesnt float.
3) "The problems are systemic.....just a fluke." I'll say it again. Unless you are just stupid, why would you keeping going back to a place where you are continually disappointed. It doesnt make sense. A rational person wouldnt. Three or four times I could understand........but twelve???
4) The admin is an optimist. More like a sadist. Do you just like to be abused or do you like to just be plain cruel when you get the opportunity??

I have no vested interest in Enterprise or any other rental car company. I dont care if they fail or succeed. I do suspect however, that there is more to the Admin than meets the eye. I wouldnt be surprised at all if the Admin were paid by a competitor. The Democratic and Rebublican partys are both indirectly sponsoring end-run webpages. Why not this guy?? Its the new way.

I surmise you are not who you say you are, your not a very good business person or you are truly an idiot. Just my guess.
