> where everything you described - hard to measure.
Quality isn't hard to measure. Where I live, in terms of pizza, there's the chains Dominoes and Pizza Pizza. I haven't bought from Pizza Pizza in over two years, because in their peak times they just crank their ovens and burn their pizzas.
I'm sorry, but when I'm dropping $50 on an order burning/=cooking. When the bottom is so black and charred and the cheese barely melted, you haven't cooked it.
Of the smaller stores, it's mostly a matter of they can't deliver in a reasonable time. One that does I refuse to order from because their delivery guys try to rip you off when you're drunk (order came to ~$75, I had two fiftys and a twenty and wanted to give him eighty. After about 5 minutes of juggling money and change between him an me I realised he had both fifty's and I just said 'I've got it', took the money back off him, gave him 70 and told him to fuck off and slammed the door - I think at one point he was getting a tip of $15 because I grabbed a 20 from a friend. The next time we ordered from there they tried it again by 'not having change').
Every time, I end up back at dominoes because their stuff is fresher, properly cooked and not overly greasy.
