Recently an acquaintance of mine was at a dinner in honor of volunteers for a Jewish hesed organization; there are both Orthos and non-Orthos among the volunteers. Many of the organization's clients are non-Ortho.
(BT"W, I consider this acquaintance's report reliable, but what do I know?) (But it sounds credible.)
The coordinator of volunteers gave a moving talk about the very big effects that very small actions can have on the lives of others, for better or for worse. Next, a dedicated longtime volunteer was called front and center to make the public Hamotzi. You could tell he was non-Ortho because he was wearing one of those shiny yarmulkehs from the box at the registration table and, more importantly, because the volunteer coordinator was coaching him ("Now don't say anything until you've eaten a piece of the bread"). As he was walking back to his table, someone said loud enough to be heard by my acquaintance, and probably by the baal Hamotzi as well, "He didn't wash."
(We note for the halakhic record that there were washing stations for those who wished to use them, so nobody needed to rely on the public Hamotzi.)
The person who noted the nonwashing must have arrived late and missed the volunteer coordinator's speech. I hope he or she has better control over his or her yap when dealing with the organization's non-Ortho clients.
