I'd prefer to keep this thread on-topic and specific to garbage can liners at the resorts.
@EdnaMode, which resort were you at? I wonder if it was a training issue or whether it's some new resort-specific policy?
It doesn't entirely make sense to me that housekeeping would put extra liners at the bottom of the wastebasket but not put a liner on the basket itself because then the trash just gets thrown on top of the extra liners.
At home, I used to use liners until I realized that 99% of the time I was just dumping the contents of the liner into the trash and not replacing the liner until something horrible got thrown into it (which in practice never happened). Subsequent to this, I stopped using liners anywhere but the kitchen trashcan and the bathroom trashcan. It might also be that I've become slightly less germaphobic over the years.
