Shorter-stick treatment

When someone's treatment towards someone or something is lower than all the previous attempts they've done in their life. Their efforts towards their 7th or 8th relationship would be so much lower than the 1st or 2nd relationship. Their efforts towards their 11th or 12th job would be so much lower than the 1st or 2nd job.

Manager: "Why are you slacking off of work, lately?"
Man: "My energy is burned-out from the previous job and I am skeptical about this one."
Manager: "Oh so we're getting the shorter-stick treatment..."

Man: "Why are you not trusting me enough in our relationship?"
Woman: "My previous boyfriends used me for my body and I've been dealing with trust issues ever since."
Man: "Why do I get the shorter-stick treatment for that?"
