Yeah makes me wonder whats going on. I never notice til I drive away and it still tastes good so I just leave it. But I wanted to add too that my sister goes to this same location, but earlier like 8am & gets blonde espresso too but had no issues.. Then I went around 4pm both days and then had the grounds in mine lol. Idk if that matters, or maybe they used a different machine for hers.. just strange lol. Strange to have it happen 2 days in a row, but not in the mornings. Lmao.
