Do you ever feign ignorance in order to make a potentially offensive comment into a seemingly innocuous question?

When I'm at work, or dealing with an authority figure, I will often take a comment like 'If you all got off your phones we wouldn't be slow/unable to handle the customers we have.' And instead say something like-
'Oh wow, how did you all get your phones to do what our store pcs used to do? Is it a new app?'
