My hon and I are neither of us religious people now. However, we both do believe in a Higher Power that we choose to call God. We pray together before eating in restaurants....however, it is done as quietly and unobtrusively as possible since we do not wish to make a spectacle of ourselves in public nor do we want to offend those out there who may be atheist or agnostic.
I personally hate it when I see people out in public praying loudly or taking forever about it in order to draw attention to themselves. IMO, these people are demonstrating a self-centered, proud attitude rather than gratitude to God or love/consideration for their "neighbor".
