You have a fair point, my friend.
We are patrons, not "clients"; still, much like it was in the courts of nobles during the Renaissance, the success of an artist depended on the goodwill (and the money) of those who sponsored them; those who fell out of favor would see their career come to a screeching halt (or, worse case scenario, even their livelihood was threatened).
Now, of course this is not the case and I'm simply exaggerating: still, like you rightly said, it is a choice to have a friendly/good interaction and Dandon was pretty much doing that, while Sakimichan is far more business-like in her methods; still, right now there is zero communication on Dandon's part, not even minimal; and while I'm a very patient individual (in my line of work, you're either very patient or you end up with a nervous breakdown... or criminal charges for assault) I'm fairly sure there are other patrons that are less tolerant of her "disappearances".
I'm curious now, who are the artists that you support?
