@Shannon1151 we always left enough dishwasher pods, washing liquid, toilet paper etc for the guest's whole stay.
Reasons:
I get really annoyed when travelling if I have to buy a whole packet of dishwasher tablets when I only need a couple.
Dishwasher tablets are cheap (when bought in bulk)
Any supplies that ensure the dishes are properly washed are well worth leaving. Same goes for bin bags etc.
Anything less feels cheap even when guests are only paying £50 per night.
