So what should you do if you get a crappy haircut?

Just wondering what you can do if you get a crappy haircut. Like one that is NOT going to get fixed until you grow it out or cut it off (and you don't want to cut it off).

Also, should you argue with the hair stylist? Is there even a point to that?

And when is a good time to go get another hair cut if you can't trust anyone to cut your hair?

What's your opinion and how would you deal with this?
