Does washing mayim acharonim (final waters) constitute a signal of meal-end equivalent to saying 'Hav lan venevarekh,' preventing a latecomer from joining the zimun?
Synopsis
The Rema rules that washing mayim acharonim is legally equivalent to saying 'Hav lan venevarekh,' cutting off any possibility of a third person joining. The Aruch HaShulchan and Magen Avraham discuss whether mayim acharonim is actually stricter than 'Hav lan venevarekh.'
