That, and nobody pushes back on what they order as you can just bill them more. We had governments move single buttons (literally, they wanted the stock application, but with one particular button on the right instead of the left), get to use a paint bucket to set colours throughout the application (not a theme, but customise by button), want different fonts, want the order of items in a table swapped, etc.

They tend to get whatever they want, whether or not what they spec out leads to a messy pile.
