What about the refillable mug that lasts your entire stay. If the mother buys herself a refillable mug and not one for the daughter (ya thats mean, its just for arguments sake) and the mother fills it up and the daughter drinks the entire mug and then the mother goes and refills it, that would be considered abuse. Whats the difference if the 'sips' the daughter takes here and there over the course of a few days total the sum of one full mug or more? The same amount of soda has been 'taken/abused'. Does the elapsed time between 'sips' make it any different? Its the same amount of soda even if it takes longer for the daughter(who does not a have a mug) to drink it. Again, please dont mistake this question as me being an , or trying to be nit-picky, just posing the question, and I have not used the rapid refill system ever so my knowledge of it is strictly based off what I have read about it.
