One thing I would note is that the press release doesn't actually use the word "refillable" anywhere - that is an assumption layered on by bloggers and commenters. At many of the higher-end hotels where I have seen multi-use toiletries implemented, they're in larger size bottles, so cutting down on per-unit plastic waste, but the caps are hermetically crimped on from the factory and can't be removed without destroying them. In the other cases, the toiletries are indeed refillable, but are locked in place. Both of these approaches are sufficiently secure in my perspective.

I also think it is funny that, ever since the topic of hotels using multi-use toiletries started to enter the discussion, so many people have come out of the woodwork putting forth all of these wild theories regarding the horrors that could be perpetrated using them. I have so many reactions to this, including...if there are really people who get a perverse kick out of tampering with what other people touch, there are much cheaper places to engage in that than fancy hotels (restaurant bathrooms, etc.)...if the thought of refillable toiletries gives you the creeps, then I hope you don't ever learn the sorts of "tricks" that housekeeping often uses...and, honestly, the worst thing that anyone could ever put in a toiletry bottle is no worse than the worst things (plural) I have ever stepped on in a hotel room or found between my sheets - after getting into the bed. I haven't died yet!!!

And agree with the previous posters as well - it's not like miniatures were perfect. I've picked them up and found them half-empty from the previous guests plenty of times. I bet that on more than one occasion I've had them dunked in the trash or toilet by a hurried housekeeper and then quickly retrieved and put in place, unbeknownst to me and no worse for the wear. Yet the minds run wild on these bulk dispensers. Simple explanation is that people just don't like change.
