Being the recipient of a favor means honoring the terms of that favor.
While there are plenty of people who are happy to help out those whom they know, this is generally under the condition that they will be respectful of the time and energy that they are putting into helping them. Nobody likes to feel like they have tried to do a good deed and had ingratitude thrown back in their face. It is something that we should all be mindful of when we are offered help.
This way of behaving is common sense for all kinds of situations, but in particular when it comes to the workplace. Showing a coworker or a boss that you are not willing to appreciate something helpful that they do for you is something that sooner or later will inevitably have real, harsh consequences. Still, there is a certain kind of individual who sees no problem in pushing the boundaries regardless. It doesn’t end well.
