Gimme Coffee

As a student at CBS, I go here quite often. I love the hot chocolate, and the prices are reasonable. They also have a stamp card, where you get your 8^th drink for free. The inside is also very cute and comfy, and they always have music playing and the doors open :)
The main issue I have here is the inconsistency. I have gotten around 8 hot chocolates here, and they are always different. There is only one size, yet all of the workers will charge me different prices (I don’t think it’s actually on the menu). I go in, and it is 20 DKK. Other times it is 25. Once it was 27. I also recall it once being in the 30’s! I understand it being a few DKK off, but not by a 6 – 10 krone difference. Also, the hot chocolate is always different. Sometimes there is whipped cream. Sometimes there are marshmallows. Sometimes there is a little biscotti with it. They all taste good, but it still confuses me.
