Without saying too much about at least one of your companions I think you might want to change that to "our companions are not obliged to provide any sexual service" :-) - but hey, if they chose to do so, so what, why not, thats their choice of course. I'm not suggesting by the way that that is the purpose of your travel service Moses, I'm SURE it's not ( and I really mean that) but of course what happens between a guide and a customer once the days touring is complete, well, that's totally between and up to themselves of course I would assume - but it just shouldn't be "expected".
