well damn dude. You just tried to scam your boss’s family, beat his son in law, and attacked his granddaughter, who happens to be OP AF. You might genuinely have the worst luck in the world.
Even if the grandfather dislikes his son in law, he will be angry at the employee for being a complete failure of a merchant
Merchants go off trust and mutual benefit, if only one merchant in a deal is making a profit from an enterprise and the other party isn't then trust in them will completely dismiss and no-one will willingly do trade with them.
Furthermore, if they belong to an organisation, then trust in that organisation will be lost.
