I think maybe he wasn't drinking when the contract was made, he might be just became unemployed and the people he's talking about left him, so he suddenly became like this. Idk, this seems odd, like you said.
it doesn't sound that way when a family man such as himself tend to start drinking especially in large some is usually an excuse to escape whats going on around them that's what it looks like (=・ω・=)unemployed wife got fed up left with the kids salesman probably came when it was all hunky-dory then it all came tumbling down caught in the crossfire can't predict those (●￣(ｴ)￣●)
Sounds more like his unhappy wife left the guy for another man and took their kid, then he spiraled into a drunken stupor and lost his job.
that sounds right too
I think the salesman should assess his potential client more prudently.
This time it's so obvious that he is a drunkard client. （￣へ￣）
