Slow service at pick and pay hypermarket woodmead

Been doing my grocery shopping at pick & pay woodmead since they opened and never been satisfied with the service there,now I have something to compare with is why I'm writing.I can see it was deliberate 4 the company to employ old ladies & all I can say is ,it is and was a bad decision because at the tills there is no urgency and we stand there for ages to get served, compared to the last few months when you had these youngsters at the tills maybe being trained or something but boy was the service fast and friendly, the manager should just review the cctv cameras to confirm my observation, the attitude of these old folks just socks and for such a big shop ,hypermarket to be exact ,service needs to quicker,hope you review whatever policy you have in place
