Most of time the Pret here is great, but the past few times I’ve gone have all been ruined by the same employee (she has a lazy eye). The last time I went, I was charged for a large even though I received a medium. Today, I went and ordered a large with oat milk, explicitly stating that I wanted oat milk because I can’t have normal milk due to food intolerances. I noticed as she was making my drink, she put normal milk in it instead, so when she handed it to me, I tried to clarify that I wanted normal milk. She then proceeded to shut me down unnecessarily rudely, claiming that I had never said oat milk, and when asked if there was any way I could exchange it, said no. I wouldn’t have minded if she just said that she’d misheard but couldn’t exchange it anymore, but she went out of her way to argue that I hadn’t said oat milk, even though I know I did and my friend with me also heard me say it. I ended up leaving because I didn’t want to hold up the line, but I’ve genuinely never had such a horrible experience with any employee before. I would give it 0 stars if I could.
