Avira > chabad just asks people if they’re Jewish and plops it on them,
So, if you feel you can help here, stand nearby and interrogate these potential yidden to help the busy shluchim? It could be a conveyer –
one chabadnik asks “excuse me, are you Jewish”? yes go to the right, no goes to the left
Avira stands on the right, asks them about their grandmother, checks out answers on his laptop, passes them further to the right to the 2nd and 3rd chabadnikim who put shel rosh veshel yad at the same time.
