This would be a shorter thread if you had asked for posts from people who haven't done something like this
.
I haven't done this exactly, but I once finished shooting a wedding, walked back to my car, proceeded to unload the last roll of 220 from my camera and when I went to attach the tape to seal it, had the roll slip out of my fingers and merrily unroll itself across the parking slot.
Thankfully, they were all shots taken late in the reception, so in the range of wedding photography disasters, it was near the lower end.
Your slip will help you in the long run - it will be a long time before you will develop film without first checking the chemistry.
By the way, when developing film, I almost never get the stop bath and fixer ready until the film is already developing.
