I mean this kindly, and I'm not responding to any one person or any one post here, but just as a short of existential idea to help others...
I don't believe in the idea of "owing" someone in this context (obviously that doesn't apply to favors or money, etc.), or the notion of "deserve"? What do any of us "deserve", and who decides that? Certainly not me. So I figure given that, I really only have to be able to sleep at night; for me, I can't live with myself if I shit where I eat in this context. I remember a boss (and a friend) told me once back on an early performance review that I should cultivate relationships BEFORE they are important, BEFORE I need them. They are more meaningful that way.
And I think back, easily half of the jobs I've gotten in my career have SOMETHING to do with the people I worked with on previous jobs. When I was laid off, I was getting desperate, and I sent an application to a job at GE (a company I had worked for previously) in Erie, while I lived in Philly. I went through the interview and got the job, and it was almost easy. Like my second day there, the HR person said something to the effect, "we basically hired you because of your reputation in this company." and as we talked, it came out that someone on the hiring team knew someone I worked with on the previous stint (someone who had been a General Manager then but was now a Vice President, rarified air at GE). I didn't cite them as a reference, but they were asked nonetheless, said good words about me, and bam.
To each their own, but industries are small, people talk, and I'm not taking any chances on what I might, in the moment of emotion, feel I "deserve" or "owe". I have to sleep at night with MY behavior, no one elses.
