I wouldn’t say “most certainly” isn’t poisoning people, it’s possible, just incredibly unlikely. It’s definitely not targeted at you, MD, even if that were the case, if your mom was the one that picked it up and you still got sick.

Have you been going there long enough to know if he’s new or not? Idk Starbucks’ layout, but at Dunks it’s not foolproof to use lower temp water for green tea (sticking to that example because that’s the one that gets me sick so badly I only drink green tea/matcha stuff if I make it myself and have an accurate temp check).

You can go to a different coffee shop, or if that’s too out of your way you can tell someone there (probably manager or assistant manager) that you suspect someone there isn’t making drinks right. He’s probably messing up others drinks too and needs a little correction (or to be straight up fired if he can’t/refuses to).
