About waiting three hours: I always thought that the reason was because in Germany they would have a small meal at teatime in between lunch and supper, so “bein seudah li’seudah” was never longer than three hours for them.
Also, my yekkishe friends tell me that R’ Shimon Schwab was a proponent of waiting the full six hours, even for those with the minhag to wait three, because in America we only have three meals.
Joseph:
I mean what does the 5.5 into the 6th mean? They start eating milichigs 5.5 hours after the last bite of fleishigs? Who has this minhag?
This minhag is actually the official policy of BMG and fairly common in the greater Lakewood community. I’m told that this is because that is how R’ Ahron Kotler held.
