Costa Coffee review: service and hygiene 1

I called into costa coffee yesterday 30/10/2011... I ordered to large caramel lattes. I found the server to be very rude... It was 20 mins before the shop was due to close and you could see she was annoyed at the customers in queue. The guy making the coffee was to busy chatting and looking around him rather than getting on with making the coffees. Two customers where ahead of me in the queue and I still had to wait almost 15 mins for my coffees. I work in the local college in a coffee dock similar to costa, we have constant queues and can serve each customer within 5 mins of them ordering their drink... The jug which was used to heat milk was very dirty... It had'nt been washed... I am a trained barista and I know that milk will not froth in a dirty jug... The coffee machine was also very dirty.. Not hard to use a cloth to wipe down after every use... And a clean cloth at that... And to add insult to injury the coffee was not nice at all... I expected alot more for my money considering I spent almost 9 euro on 2 coffees... I will not be returning to this store..
