Time will tell, but make sure you remember. People can be sneaky including the fact that a repeated offense may be dissimilar enough in their minds because they aren't aware of the emotional root. If you need to educate them, please do. Altering or refining your original request may be in order to, although don't try to use it as some source of control; meaning to keep them on the defensive or in exchange for something you are doing.

At the same time, the momentum can be an issue with them if they've been doing things a certain way for a long time. Now while we should never accommodate abusive behavior that repeats, other behaviors may require a more vigilant response on our behalf. If that's the case, make sure you establish what is going on. You are, in fact, helping them to remediate their behavior. While you may benefit from the change, it is not your responsibility, so some type of barter may be appropriate.

Most importantly, look out for others too. It's not just about you. Plenty of people know who will let them get away with things. If you see people behaving better with you than with others, bring that up too. After all, if they get in the habit, an infraction may be coming your way soon, too. And, ultimately, if someone else is suffering, you are paying a price.
