What you hate about contractors..

[Steve Yoo]

Hi everybody, I am a contractor and I am very curious what most of you feel about contractors. What do you like about us and what drives you crazy. If in a perfect world what would that contractor be? 

Reason I am asking this is because I am the other side of renovation and I want to know how I can be a better contractor to work with and if I am also do things people hate. 

If would be very helpful if you BPs can list them and even get into details 

Thanks, Steve
