Handling a snake right after they eat really isn't a good idea. They need about 48 hours to fully digest a meal. Moving the snake after eating can cause regurgitation and possibly a bite.
When I first got my snake, several people (ones who have never even owned a snake before) tried to insist that I feed her in a separate tub otherwise she will get aggressive and strike every time I put my hand in the tank. That's completely false. I feed in the enclosure every time. She knows that Tuesday is feeding day. I've had her since February and she has never even tried to bite me and hasn't skipped a single meal!
