My Korean rat snake is a lot like that- he hates being handled because it means being restrained- when I need to take him out, I take away his hides & he'll usually dash around his tank but he obviously remembers my touch & the process, as he doesn't try to bite- he's just squirmy while I take him from his home & then let him crawl into his pillowcase while I clean his home. His pillowcase is inside a secure plastic container, I might add. If this snake was ever loose on the floor, I'm quite sure he'd been in full defense mode & not at all fun. But as it is, he "knows the drill". He's not easy to restrain, as he's a very robust (strong) six-footer- he only tolerates brief handling with a light touch.
