We have a client that asks for changes to a portal regularly.  They pay so we do pretty much whatever they want.  Once in a while we can offer a better way of solving the problem.

Lately there have been a couple of changes that sounded difficult to pursue.  Upon further investigation we realized: our software can do this now, we have the data needed to provide the solution and (this is the best part) we had originally developed the feature that way and the customer told us to shut off that part n months ago.

Of course, we turn the feature back on for them.

It just must be nice to have so many resources (time, money, us) available to you that whimsical changes are acceptable.  AndI thought you had to win the lottery to do that.
