Clients: Part 2

And its annoying because you just cant tell how much work would be involved, and if you over estimate then they may decide to go somewhere else and if you underestimate and when the project is finished and you send them the bill they get upset and "you told be $XXX", "but I did spend the last 2 weeks working on it putting aside other work". Oh and the other thing that gets me about clients are the ones that ask you to get something done quicker and then dont bother to even collect that day and wait a week, when you could have comforatbly done it over the the week.
