I don't want to argue with you.  Being canonically a member of the Ukrainian Greek Orthodox Church can mean many things.  I don't know how familiar you are with the Liturgy.  
I have been at many Liturgies in churches in Ukraine with no pews.  Yes, some people pray on their own (kind of like RCs who pray the rosary during Mass).  That does involve making the sign of the cross.  Since we bless ourselves 3 times, to RCs this may seem like excessive or random or compulsive, or who knows what......
People do walk up to light a candle.  Icons are kissed if there is a procession and the priest walks it up to people, or when people pass the tetrapod (I don't know the English term), or a side altar.
The people who come to Liturgy to pray do not move around randomly, or under some impetus from the Spirit.  Those who come for a social occasion, or because that is what one does -- yes, they do go out for a smoke, or to talk.  But that occurs, in part, because Liturgy (with sermon) is long.
