If I'm going to single out one outstanding factor affecting YMMV, that would be hygiene (body and mouth odor is an absolute mood-killer). In my experience, kahit di masyadong pleasing ang appearance ng guest basta mabango at respectable ang kilos, that is almost half the battle. And if you had a great experience, magbigay ng konteng extra and this is for when you get back. These theras, they do talk to each other and they also have avoid list.
