Waited 40 minutes to get 5 drinks -- 3 of which were wrong. When I approached the lady making the drinks she yelled at me and told me that I made a mistake. In a crowded shop I didn't want to create even more commotion than was already there so we left with our wrong drinks. She forgot tapioca in two of them and put maximum sugar in my dad's drink, which was asked for without sugar. He's got diabetes so this was mildly infuriating as he couldn't drink the drink he just waited 40 minutes for. Total for 5 small drinks came to $30 or so.
