For the past several weeks, we haven't been able to get refill water anywhere. We normally use those Glacier refill systems inside of Kroger or Randall's, but lately they've been empty, and no water comes out when we press the button. We've tried what seems like every location in the Houston area, and we haven't been able to get our refill water anywhere. Does anybody know why this is happening, or which locations have working water refill stations?
