Worst ever rude and slow staff

I went to pick up my sons prescription today (he doesn't live with me) I approached the woman behind the counter, I said I'm here to pick a prescription for my son whose name is xxx his address is xxx before I could finish saying his address ( my chemist always asks for address) she interrupted me and said I don't need the address,! I hen told her reading from my phone the item I was picking up at which point she told me to wait outside. There was no other person in the shop at the time.. the attitude of this person was offensive. When she called be back into the shop she said two items will be £ I said to her I only need the tablet I asked for she puffed and said well the other will have to go back. She then opened the bag I told her the new talent was a trial and said the dr doesn't normally give two months on a trial. It was nothing to do with her what the dr has prescribed!!! I woul never recommend this pharmacy because Of the rude and offensive none caring attitude of this Person...
