"Do what you had to do" - Does this mean you put you desire to have your new pet in advance of his health? I understand people work, I work, hell, most weeks I put in 55-60 hours, but I also make sure that when I've got an animal (any animal) coming in that I can either have it delivered to my work address where I have a temporary holding setup done, or that I can pick them up or get their delivery from the drive when they arrive.
It is not all that matters is that he arrived alive and well. It's important, yes, but you said it yourself he was cold to the touch when you got him.
From what I've gathered since joining this group is that responsible keeping is the #1 goal here. I align well with that, and what you describe above is not responsible. I am sure more than one person on here has told you that this shouldn't happen. I hope you don't let it happen again, but if you do, I pray for the safety of your future snakes.
Best,
Paul
