Dear Dominick,
I've never been to a Mass where someone who preferred to receive on the tongue was refused.

I had the unfortunate opportunity to witness someone, who knelt for communion, and was *almost* denied. The priest told him to stand. Some words were exchanged, the young fellow remainded kneeling (with his hands still clasped in prayer), and he finally received on the tongue.
This young fellow was literaly chastised by the priest during the "announcements" (aka "two minute warning") by way of the priest's condescending lecture on "proper 'posturing' according to the GIRM."
It was heartbreaking to say the least, I vowed never to return to that parish (which happens to be my "neighborhood" parish) again. Only in hind site, I wished I had written the Bishop and let him know about it.
Heck, even I was guilty of forgetting to say "Amen" as I took on the tongue....The priest literally held it back until I said "Amen."
I was so used to the priest saying it during the old latin rite I usually attend, I think I might have been most likely included in that little post communion "lecture" lol.
