Twisp Cresta Shopping Centre - terrible service

I visited the Twisp kiosk at Cresta Shopping Centre around 12:15 today (30 Sep 2017). The women behind the counter was busy with another client, which I understand so I waited. She explained to him how his device works, which I also understand... i was also once a new twisper, so I waited. Then he decided to test some flavours. While he debated what flavour to get (now I have waited close to 10 min already) I asked the women behind the counter if she can quickly help me while the other client decides what he wants to buy. I just want Polar Mint flavour that’s all - I will be quick. She said no he is not deciding (which it looked liked to me) he is buying.... with a very bad attitude. Then she and the client churped me and said why don’t I go somewhere else! Needles to say I walked on! This was my second bad experience at the Twisp Kiosk in Cresta Shopping Centre, and will definitely not be back for more bad service and rude sales behavior.
