I have had varied experiences, most of them good. This never really was as big a deal to me as it has been to some, I guess because I spend a lot of time in gyms and am pretty used to locker room toiletry pumps.
That being said, I am curious as to whether the intended effects (reduction of cost and waste) are actually happening. Pretty much every piece of consumer research ever conducted shows that the more of something you give to a consumer, the more they use. This is how Costco gets us - we buy their stuff on the allure of low unit prices, figuring it will last a year, and we blow through it in a week lol. So now that guests can just pump away, will be curious if the data bears out any cost savings or rather an increase.
