Nestle staff is not rude, but they aren't trained properly because their main clerk in their office does always forgets our membership number when we go there to get the bottles. I only hate is their delivery schedule for our area, they deliver new bottles to us at Friday. Nestle water is heavily used everyday and bottle gets ended in just 3-4 days. We used to drink filtered water, but since but when guests visit us from outside countries, they only drink Nestle. Plus, nestle water have some salty smell, but local water companies don't have this type of smells and that.
Still Filtered water > Electronic water dispenser which requires Nestle water.
