Retics are one of the absolute few snakes I legitimately enjoy handling/interacting with. Even the strength of a 12' captive animal is impressive!

If that retic is a female, I sure hope you got him to order at least the 6' boamaster... Looks like a normal mainland tiger- which seem to (from my experience) always grow just a bit bigger than other morphs do. My tiger is somewhere between 17-18' foot at 4.5ish years old...

Make sure to also tell him- always feed in cage, and tap train the retic. Always use paper towels to reach in and tap the snake first before handling, to remove feeding response.. I cringe every time I think of someone dumb enough to feed an adult retic out of cage, and having to deal with a retics feeding response in an open environment- accident waiting to happen.

If he does end up needing to get rid of it, let us know- I'm sure there are several of us here who will be more than willing to take him off his hands.
