Walmersley Chippy in Bury

I always come to this chippy when I'm in the area and the food & service is always good. However todays experience was not the usual nice experience. This is not a review about the food as this was 10/10 as per usual, the service is what has let this visit down. It was very busy when we visited and I understand that given the noise level when you ordering things can be missed, we are all human. When I pointed out a missing item I was told by the lady that took my order that "you didn't order one " in a really rude manner, now there is a big difference in someone not hearing something and someone not ordering something. It felt like the lady wanted to have an argument about it. Yes this is a popular chippy and a very good one but I think the owner needs to train her staff in customer service. The correct answer should have been "I'm sorry I didn't hear you ask for a buttered muffin, let me sort that out for you". Instead I was left stood there in disbelief being made to feel like I was lying. What made it worse was that the owner was stood right there let her staff member treat a customer in that way, she just stood there letting her staff member go back and forth over a buttered muffin!!!!
