Ok so I ordered 6x pearl milk teas for me and some friends to go at this location on wednesday one out of the 6 I drank had a piece of scrap metal from the metal scrubs so I'm guessing they didn't clean the drink dispenser properly because as I was chewing on the tapioca I felt something in my mouth that wasn't right and it turned out to be that, I called the store back to let them know what happened the guy just apologized twice and said I'd get a free drink next time.
Also note I wasn't pissed off or anything i just wanted to them them know about this and that their cleaning should be done more carefully
Anyways still got my receipt don't know when I'll come back again, I just called to let them know what I found in my drink so hopefully they do a proper cleaning of their drink dispensers next time
