Sure, lots of big animals are gentle. However when something the size of a car decides to gore you or rip your spine in half, there’s nothing you can do about it
A snake can't sprint at you at 25 miles an hour and then rip you in half like a phone book as soon as it sees you. Nor would it. A panicked gorilla placed in a strange location like a mall will potentially kill anything in sight.
Just don't go into corners, it's 24 hours and only 5 snakes. Go to the Asian imports and get a mall ninja sword if it makes you feel more comfortable. The snakes are going to fuck off anywhere small where they feel protected... just don't go adventuring and you won't have any snek issues.
Now if it's 50 mambas that definitely changes the calculus.
