What are the types of clients from hell have you come across in Malaysia ?

From my experience so far..

"Can you take out the black person from the picture ?"

"We're not going to pay you the remainder because we were unsatisfied with your service. And we're going to use your design anyway."

"You should be able to do it without extra cost mar. It's a simple job right ?"

"Why can't you lower the price ? We're in this for the long term."

"I want to build something like Facebook. And I only want to spend $ amount."
