No two refrigerators are alike and I have a hard time refilling my water bottle using the water dispensers on them.  Some of them are just next to impossible to not make a mess.  I figured out which ones those are and I don't try anymore. :)  Most fridges are also stainless steel which streaks if it gets wet too.... not good.  :( Molly, Sookie and Sawyer's house is the easiest.  I am refilling it every time I am there!
