I grew up Methodist. Communion isn't an everyday thing in that denomination, and one of my first times was memorable. My friend decided she really liked the bread and grape juice and went up after services asking for seconds. The poor usher was flabbergasted
It took DH about six months to find the right way to ask where our church got their communion bread because it was just that good (Kroger's store-brand Hawaiian bread, if anyone's curious!)
When I was elementary school age, I was a communion SS. I grew up in a Presbyterian church, and our particular church only did communion every 3 months. Most of the P churches in our area would get the bread from one particular bakery, which would make huge sheets of shortbread. These were scored so that you can break them into smaller pieces.
In other words, we had cookies as our communion bread. My Mom would let fidgety me leave church once during the service, where I usually just went to the restroom or explored around for a few minutes (I knew the limit of my time "out"). While exploring one glorious Sunday, I found where they stored the leftover communion bread - the freezer downstairs in the kitchen where no one was on a regular Sunday. And where no one would see me joyfully helping to "dispose" of the leftovers.
