Let me rephrase this for you.
“How much of a selfish prick can I be and still be privileged enough to receive a full treatment”
The way you worded it was rude in my opinion. If someone showed up to your work within a few minutes of you going home after working a 12 hour day…. Would you want to stay? Would you provide the best effort for this “overtime”?
Think of it the other way and try to be considerate. It isn’t all about you.
