Daft question of the week coming up here.

I have done a few long haul C runs recently and when you are served a meal they always bring you a fresh salt and pepper pot with each course.

I wonder how much these things cost ? and how many never get used and thrown away.

I always think that pepper is quite expensive when buying it for my kitchen, so I wonder if someone can shed some light on this amazing subject that is obviously keeping me awake.
