Definitely the less experienced people who recommend and encourage feeding in a different enclosure.
On a set and steady feeding schedule your snake will know when it is time to eat. It will not mistake you for food. My snake is always ready to eat feeding day, rat or no rat. He will strike and try to eat anything on feeding day, because he knows for a fact that he's going to eat that day. Only time he's ever bit me is when he's in shed, but a defensive strike and a food mistake bite are waaayyy two different things, shouldn't be mistaken either.
Moving a snake from and to feeding tub are probably #1 reason why new snake owners get bit.
