There are two kinds of sloppy: sloppy because it's micro-managed by pointy-haired bosses (in this case, yes, run away!) and sloppy because they just don't know

There are two kinds of sloppy: sloppy because it's micro-managed by pointy-haired bosses (in this case, yes, run away!) and sloppy because they just don't know better. In the latter case, you can experiment as you like and bring improvement; it's an interesting challenge and it's rewarding. And if it's a relaxed and funny environment, it's even better! Or you could go with the guys that know everything and are so proud of their system (system that is sooo complex and hard to understand). In both cases you'll learn something valuable, anyway.
