Worst service ever

Service at this KFC outlet is the worst ever. I go in to place an order the lady says the don't have cup cold drink so my order will be R66 instead of the R59 because I will have to take the 440ml cold drink. She then proceed to ask the flavor of the drink but now she fails to tell me that any cold drink except no sugar drinks will cost an additional R2. I only realise this when checking my receipt. Issue number two is the employee didn't know how long my order will take because they chicken is still cooking - but she was supposed to tell me that before she took my order. Issue number three is the are people waiting for their orders due to Covid 19 I decide to wait outside in the car thinking that as soon as the chicken is ready my order will be prepared. When I go in I find a gentleman frustrated because his order was given to another lady they thought she was with him - which means this lady might have gotten an incorrect order without noticing or she saw a gap and used it to her advantage. Back to my order- I give a lady my receipt assuming that I am collecting only to wait another 20min while it is still being prepared @ KFC please train your staff properly , have standards, have expectations of what you want your customers to experience and monitor that. Teach them to value the customer and the business that is helping them to feed their families.
