On his blog, Ben Witherington plugs his book Making a Meal of It which looks like it might be worth reading.
I was more frightened by one of the comments which gave a link to The Remembrance Cup which might surely be the 'Pot Noodles' of the Eucharistic elements, but without the dignity of Pot Noodles.

There is often no reading of Scripture, no 'epiclesis' - a call upon the Holy Spirit to act before the words of institution, no thanksgiving prayer, and no symbols, ie. no loaf of bread and no chalice and the significance is usally reduced to a mere memorial -an academic recall of what Jesus did. Believe it or not, I have personally attended churches where the sacrament is treated in a cavalier fashion - a "self-serve" station is available throughout the service; or a declaration there is no time in their worship services for the Sacrament - do it if you wish in your small group!I'm not even sure what to say. Other than, please Lord don't let this happen here. And people wonder why the British Methodist Church insists on 'good order'. I think the link and the quotation are good examples of what can happen without 'good order'.
