Another question:
If it bothers you that someone is constantly “playing with their phone” during davening, why can’t you just go over to them and be mochiach (rebuke) them? I mean at the end of davening one time and in private.
Does it mean that you maybe haven’t even given the person a Shalom Aleicheim? Maybe you and interacted with them over time in a manner that they would genuinely feel that your chastisement is meant out of a genuine concern ) for their ruchnius?
If you’re unable to achieve that “ve’ahavta rayecha kamocha”, if one can’t do anything real about it, maybe one should at least learn not be “sickened”.
