Subway in Rotherham

I am a regular Subway customer, visiting at least once weekly. I was absolutely disguised and disappointed to get such a disgraceful and degrading service at Drummond St, Rotherham today. Myself and my sister agreed to visit Rotherham and change our weekly Subway meal to that of Drummond St as we was in the area. We were abruptly asked to "wait love" and subsequently two customers who came in after us were served, we said nothing. Thereafter, we ordered a foot foot meal deal, with a drink and cookie. When the assistant was filling the sandwich, I asked for olives and she rudely responded with "okay I am getting there" and sighed under her mask, again we said nothing. Then upon payment they just handed us nachos and a foot long Subway and charged us - this is where things got bad. The exact words I used was "we ordered a meal deal" and we was given an onslaught of words including "no! you didn't", "what do you want?" and lots of mummering under her mask, responding with its an additional £1.88. When asked for the receipt to clarify what we was being charged for and she raised her voice and said "I have thrown it!" This didn't end here, a young man came without uniform and asked what we wanted, we relayed the story and he was being extremely rude and asked us loudly "which cookie do you want?" - he was no different to the staff member we dealt with earlier. I stated "chocolate" as at this point I was ready to walk out, to our amazement after all the staff had said to us and treated us - he responded with " a please would be nice!" At this point, I said "I am only dealing with you the way you have dealt with us the moment we walked into this store and for the past 10 minutes" After this, in front of all the customers he walked away and in a loud voice just kept on going and going stating things like "you're rude", "I don't have time for you", "go elsewhere", "look at yourself" - we have never ever in the past 32 years been treated like this in any store we have visited and purchased from. No apology, no empathy, no customer service, nothing! We received our order and decided to eat out on a bench (which we normally don't do), another customer approached us after a few minutes and said that store is known for its poor customer service. I have contacted Subway complaints and will update as soon as I receive a response. I have never ever complained in the past 32 years to any multinational corporation but I am very upset right now, for the right reasons.
