A dissapointed customer - Krunch Alice Lane

I am utterly disappointed on the service I've just received from Krunch Alice Lane. I waited over 30minutes for a smoothie I ordered, and the only reason I eventually received this smoothie is because I asked the lady who took my order if she had processed it, as I had been waiting for so long and she hadn't given me a slip when I made the order. She then went to the back and a few moments later I could she see her rushing to make the smoothie (This is the same lady who was in front taking orders at the till) - I am not sure how it works, but I would assume that the guys stationed at the back/kitchen would be the guys responsible for the preparation of the order at the time. But anyway, the lady rushed and made my smoothie, and can I just add that it does not taste good at all (and this is me being VERY polite). In the midst of all this, there were a group of ladies , that work at Krunch, arguing/having a discussion on who should/should not take leave etc - so I would argue that there was enough capacity to assist the lady who placed the order - If she even did place this order! Might I add that this was also after lunch hour (2pm), I was the only one who had ordered at the time, so it was not busy at all and therefore would have not expected to wait that long for my order. Furthermore, I have ordered from Krunch during lunch hour and I have never waited that long or received such poor service, hence the disappointment. I know this may seem small or petty but time is money, and when I pay for something (whether a big or small amount), I expect to get the value I'm paying for. This is the first time I'm experiencing this from Krunch Alice Lane, and I often buy my lunch there. I do certainly hope it will be the last!
