KFC Bloubergstrand has the worst cashier ever

Absolutely pathetic service from KFC Bloubergstrand, I am a regular customer to this store as I live in close proximity but this was the worst experience I have ever had, I placed an order for a KFC meal that included 2 no sugar fountain sodas, I am not a big fan of that so I decided to pay a little extra to get the normal soda instead, once the order was ready the cashier with no people skills whatsoever rudely stated that there is no cooldrink and no water, they only have cream soda, I was not happy with that and opted to just get my refund for the extra and paid as I did not want the cooldrink, the cashier refused to give me my refund and that is when I realised that this person does not care about customers and she is going to give your store a terrible reputation, there should be no place for people like this in the front of your store, you should teach your staff how to speak to customers and how to handle queries as this person was so frustrating to deal with, hated my experience, yesterday I also visited the store and they also did not have cooldrink but the previous employee was professional and we could have a polite and decent conversation and managed to come to an agreement.

Have to hand it to the supervisor that was on duty that was speedy to assist but overall, it didn't need to be a miserable experience for anyone, I think my request is well and truly fair, the store does not have what I am paying for, simply return my money and keep the item that I do not want, I am saving you money by not taking the sugar free fountain soda.

I can understand that an item might not be available but what I can't accept is a rude person giving me grief and speaking down on me like I am in the wrong or I am asking for more than I am paying for.

I am a grown man, I have children that are probably a lot older than this young lady and I am so disappointed, gosh, I am so unhappy and advise the owners to train their staff accordingly, my advice is to immediately move the employee to the back so she does not deal with customers until she is trained on how to speak and how to deal with customer queries.
