What happens here is that the buyer "kicks back" a fat contract to their sales buddy who took them to that great golf resort. Or, if the terminology is wrong, you can just say that the sales agent bribed the buyer with a golf trip in order to get the contract on better terms, to the detriment of they buyer's company. Either way, golf games paid for by people trying to sell something are obviously morally and ethically wrong, and would be extremely illegal if they happened with a government employee.
