I generally like Real Fruit because they always have cheap milk tea and mango smoothies, AND give you a stamp for it. For some reason though, this place doesn't give you stamps for the milk tea, which is weird because the one at STC had no issues giving me one.
Also, I would agree that the customer service isn't all that welcoming. The workers don't really smile or show gratitude, but for the price, I can deal with it, haha. Maybe I'm just salty because I got refused the stamp... lol
