I'm quite certain it influenced his thinking. I fail to see how that's reflected in his "how to have a good dinner party" ideas, other than that the servants bringing the food to a southern US dinner party would have been enslaved, and the ones bringing them to a northern US or UK dinner party would have been free. They wouldn't have been invited to chime in in most cases. Kind of an unavoidable consequence of having servants at all. Even at a self-service potluck, someone has to provide the utensils, the drinks, the food refills, and the cleanup. Usually someone volunteers for that role because it's easier for them than making a dish, and it is contributing to the party.
