UPDATE: So, unfortunately circumstance brought me back here. I needed to buy something in order for someone I was with to use the facilities. I decided to buy an Espresso Macchiato for 8.9zl. It rang up at 10.9zl. I asked the woman again if she had rung me up for the Macchiato. She affirmed this and I thought the price on the register was just wrong. When I counted my money, while rushing out, I realized she had really charged me 10.9zl. If it was 2zl for the to-go cup, then kill me now. I should mention that the place was absolutely empty. Figures.
