For those of you who take your film to a retail store for developing...

I'm trying to determine among the major US retailers who consistently does a good job (or not so good job) developing color print 35mm film. Yes -- I realize every individual store is going to be different, and processing is only as good as the tech working the machine. But I have to believe that there's some commonality among the major retailers in the equipment they invest in, the processes they use, how they train their people, etc.

Maybe I'm being anal, but I've heard horror stories, for instance, about the drugstore chain that trained their people to open the canisters in the room light (?!).

I'm not interested in prints, just a well processed negative.

What are you experiences? Who do you regularly take your film to?
