As I am sure many of you know, there is a historical practice of spitting during Aleinu. A discussion of the origin of the practice can be found here.
I have davened at Conservative and Modern Orthodox shuls, but have never seen anyone spitting (not even a fake little ptoo-ptoo). Are there some communities in America where this minhag is still common? What about in Israel? Do they use a spittoon (like a little cup kept in their shtender) or spit right onto the floor?
