I don't like qualifiers. And what IS an "interesting crowd" restaurant-wise? There are diners, eating. I don't see what makes them boring or interesting, since the person saying that they're interesting isn't sitting with them or talking to them. But I buy the nice decor and the good food - that is the only thing that would get me to the restaurant. The crowd I could care less about.
And if one is spending time with someone they care about and love then it is automatically time well spent - no qualifiers needed. Just as spending time with a bore is time wasted - no qualifiers needed. This is just my peculiar world-view, I suppose, but it suits me just fine. Others can qualify all they like. There was an interesting crowd at McDonald's earlier today and I spent some quality time ordering a Filet o' Fish.
