Most do, but some don't, one of my sources (the uni where I work) have a self service C-41 machine, so you'd have to us a little machine to take the tongue out 1st, this way, the cans are perfect. Admittedly, opening the top is a much quicker way to get the neg out, taking the tongue out can be a pain at the back side.
I have tried putting the bits back together, but it just doesn't look good enough and is harder than imagined.

So if anyone can help, it'd be most appreciated.
