BYO shampoo minis and what do hotels refill their dispensers with?

[Port Power]

I have noticed what’s on the housekeeping trolleys in many hotels and where applicable, they have been the branded product. Mostly the large dispensers have been locked so that the contents cannot be interfered with. Some hotels unlock the contraption and refill, others replace with a new full bottle. (A couple of times I have rung housekeeping to come and refill an empty bottle, too. Don’t just grumble to yourself!) I carry a small body lotion for use in the cheaper hotels that don’t supply that product. I wouldn’t use refillable bottles that aren’t secured, but have not come across any as yet.

I prefer pump packs to those stupid little L’Occitane bottles though. It is practically impossible to get any product out!
