I think you made the other posters point. You had a bad experience once and still bought from the same pizza joint, possibly a couple more times to have further bad experiences. Maybe it was price that drove you to continue in your effort to get a bad business to give you a good product? Maybe you wanted a change and thought the previous experiences were anomalous? Regardless it took you some time to figure out that the business was bad. Now repeat that for every pizza joint in NYC, not so easy... Customers don't have access to the kitchen, the ingredient supply chain or background checks on the employees. Looking at a coupon flyer doesn't tell you that the staff is rude, the pizzas are bland and the employees don't wash their hands. Some companies work by pumping out a poor, low cost product and wait for the suckers to bite or the previous suckers to forget or think it was a one-off. There are also a lot of people who will put up with crap so long as they think they're getting a deal.
