By Pesach my rav told me explicitly that most frum people are not yotzi.
????? ????? Even a minimal shiur?
he Gra holds that mayim achronim has the same dinim as mayim rishonim (you need to wash with a kli, with a revi’is, full hand).
A matter of machlokes in shittas HaGra on the revi’is (even though it says it in Maaseh Rav)
I saw in a sefer that there was one gadol who said that a person should consider the possibility that maybe he never washed for bread correctly once in his life!
