Alright, please excuse me for misunderstanding your message, then. Apologies.
But of course I will stand by my own opinion as is. I was thinking about it and the difference as far as I can tell in the ritual surrounding distribution of communion that might account for the RC attitude is that, all other things being equal (so as not to compare a 3,000 person RC parish to a 40 person Orthodox one), there seems much less to do in the RC model. I can't receive in the COC yet, and it takes about 20-25 minutes to distribute communion in the parish I now attend, but that time lets us get through a few communion hymns, which are generally the high point of the liturgy, as that's when the people are at their most energetic and joyous. Contrasting that with my memories in the RC church, I don't even remember there being multiple communion hymns (though there probably were), meaning that there was a lot of space filled up with silence or some soft, droning keyboard/organ. I could see how a half an hour or more of that would get tiresome. Perhaps the RC could lessen the apparent dread at having long communion lines if there were more to do around it other than wait for it a while, then to back to your seat and sit quietly.
