It's a consumer rights issue. Complaining about a service that is less than satisfactory is a right. Whether one goes above and beyond a certain point is a subjective determination. Look at it this way. Say you go to McDonald's, you order a Big Mac, you get your Big Mac. Well, the 16 year old punk making your Big Mac thinks it's funny to put a a fly in it, then shoots a snot rocket in it for good measure. Being a conscientous consumer, and seeing the smirk on the kid's face when you get your sandwich you check it. There you find your dead fly and booger.
Do you say, "Excuse me kind sir, there is a dead fly and booger in my Big Mac, if you don't mind could you please consider giving me one without some time in the distant future, only if you feel like it?"
Hell no, you say , "This is totally rediculous, I pay for a quality product, the fact that you and your company provided me with a product that myself and any other reasonable customer find totally unacceptable is unforgivable, fix it now, or hear from my lawyer".
Too many people today are willing to accept products and services that are not all they can be, simply because the provider of those products and services is blinded by their temporary success and becomes so complacent that the customer's voice is not heard.
Many, many people have voiced their disgruntlement with Pizza map on these boards with no response. When no response or mitigation of the problem is provided it is natural to take ones complaints to another medium and up the intensity a notch.
In summary, pizza map is a big hairy fly swimming a green booger in my Big Mac that is Aces High, my favorite hobby. Everytime this map comes up, the provider of this service for which I am paying is going to hear me rant and rave, period. Until the day it is fixed (ie: no more pizza map in rotation, or at least not a week of it, 25% of the month).
