I tried the past two days to find this story on my own, but I can't. Let's hope one of you read this story.
The main character is manager of a chain of supermarkets or something like that. His ex-wife cheated on him and is married to her lover who runs a couple of sandwich shops. They had a daughter which the ex-wife tried to keep away from him while she grew up (I believe there is mention of some sports and camps so that the father couldn't spend time with her).
The main character was rather timid/took all his ex-wife dished out until his daughter told him she is going to get married and wants (or rather her mother wants) her stepfather to give her away.
That leads to the main character realizing he is due some revenge. He starts his own chain of sandwich shops in direct competition with the new husband of his ex-wife.
He also discovers that the soon-to-be husband of his daughter is cheating and intimidates and bribes him to not show up for the wedding.
I also remember that the other sandwich shops were closed by health inspectors while the lover is stuck with jury duty.
Meanwhile the main character sues his wife for alienating the daughter. And he starts dating a cashier from one of his stores that was in an abusibe relationship.
While I can remember a lot of details, all my searches turn up nothing. I don't know wether that's because I am misremembering some things or because the story is no longer on SOL. I know that I read it on here in the last six months or so.
I would really appreciate any and all help. Thank you in advance!
