She frequently complained about the Talenti line having issues. When it was acquired they had contractual responsibilities to produce the gelato a certain way. One thing I remember is it used sugar in granular/powdered form, whereas all the other ice creams used a syrup. So they had giant hoppers of sugar, which of course are a big explosion hazard so there was a lot of equipment around that to keep it from blowing up.
I do remember the tight lids thing, heh. They were well aware...
Ben & Jerry's is also a Unilever brand but manufactured in Vermont (but largely not the one that everyone tours). I think that one is even more complicated because of all the little mix-in ingredients and stuff. And I remember at one point they had these "pint slices" which were packaged as rectangular prisms and had to be cut by enormous, very sharp knives, which caused a fair number of worker injury events.
Since then she's moved on to manufacturing other things. As a purely digital guy, I'm always fascinated by the "real world" things that physical goods have to deal with.
