LPT: Starbucks tap water is cleaner than the water bottles they sell.

Long long time ago in a small faraway town named Seattle, Starbucks realized that the key to good brewed coffee is clean consistent water. As a result most - if not all - Starbucks locations contain a three stage water filter (look up Pivot PVK200-SBUX-WFIL-CFG3A) to ensure the cleanest water available, which is the exact same water you get if you ask for a cup of tap water. However the bottled water they sell at the cafe is typically overpriced and contain trace amounts of microplastics. Most places will give you a cup of tap water for free allowing you to get the cleanest water for the greatest price.
