He just told us that our chief developer.
From the bank came the requirement to remove from one form the button with which the user was deleted, i.e. they decided not to delete them at all.
The task was sent down to the programmer and after days he reposted "Everything is done".
The module was handed over to the bank.
A week later, a new error was corrected.
The essence of the error was that the button was left, but it could not be pressed... it ran from the mouse across the screen.

The programmer was repelled by the argument that he exactly performed the TZ, the user really could not be removed from the system.
