‘Costco would never’: Sam’s Club shopper shows why you should always wait for soda bubbles to clear before drinking from soda fountain

If you're a fan of Sam's Club's soda fountains, a recent TikTok might have you second-guessing your next refill.

In a video posted by TikTok user @gettyworld, the Sam's Club customer fills their cup with Mountain Dew at a soda fountain. As the carbonation clears, it reveals tiny black particles floating in the drink.

Even more concerning is that this wasn't an isolated incident. In a post uploaded just one week prior, the TikToker documented the exact same issue at the same location.
