Here's the deal:
The nose rub is an issue - not because it happened during shipping, but because from the other photos it looks like a pre-existing condition that should have been disclosed.
The shipping issue is an issue and it is NOT an issue. All boxes should be labeled and delivered in accordance with both carrier and federal requirements.
The problem is that the majority of the people use a white box, mark it Live Animals and think they are on some sort of moral high ground compared to someone who packs the snake in a brown box without the live animal mark.
That does not wash.
If someone is going to attempt to call someone out on improper shipping practices, you better darn well know ALL of the rules you should be adhering to.
That means that simply slapping a "Live Animal" sticker on a white box and getting a signature should not be the end all. It does not conform to the Lacey Act and it does not conform to Fedex's own rules by which they hold your live animal shipper certificate.
