Oh we are ALDI! What customer service?!!

The above sentence was said to me (more or less) by the store manager at ALDI branch in Sheffield London road. I do sometimes shop from ALDI if I pass the store on my way but not often. I don't like all the products and mainly buy fresh veg and fruit if I go to the store. Last visit bought some veg and fruit and was queuing with a lady with one chewing gum behind me in the queue. The cashier asked if she could serve that lady first because she only had one item. I agreed reluctantly as I was in hurry but because I was put in a awkward position I said yes...I usually offer this myself if I can and did not appreciate to be asked but apparently this is the store policy to ask!
As soon as the lady was served, there was another guy behind with 2 items in his hand and he asked me if he could also get served before I did and I refused! I said to the girl at the till and I did not mean to be awkward but I did not appreciate him asking me and if that is the policy I could be in the queue forever if everyone behind me had one item to pay for! She was not interested but I did not expect her to be as I know how they operate and all they are interested in is to scan items and you pay without delay, so I shut up and let it go. When I was putting the shopping bag in the car, the same guy from the queue appeared next to me and started being sarcastic. I told him where to go and he deserved the reply he got, he disappeared but then I decided to share my experience with the store manager. When I was taken to him, I shared my thoughts and said I did not think this is nice to ask customers to give their turn to other customers as this puts that person in an awkward position and that it gives some people the opportunity to be rude. He said but we are ALDI, we can only give you cheap products because of our til system. Many people don't like that they have to pack their trolly after they pay but we are ALDI. We cannot control how other people behave....". I understood what he said and partly agreed and I said I did not expect the customer service of Waitrose from you but it does not mean you should not care how your customers feel! He basically was not interested, was not empathising at all and kept repeating " but we are ALDI"... and at the end I said so your answer to my feedback is that you are ALDI and turned and he was like, humm yeah...
So yes I know you are ALDI and now I know ALDI means cheap products, cheap customer service. Will not buy from you again not that you are bothered!!
