Why are so few till points open yet again at Pick n Pay, Claremont, Cape Town?

This is definitely not the first time I'm complaining about Pick n Pay, Cavendish Square, Cape Town, whenever I go to said store, why are only 2 tills open at the "express" check out line, I eventually found Shanaaz, the damager at said store, & her excuse was rather pathetic, please wake up, it's Friday afternoon, people want to do their shopping & go home. Pick n Pay, please STOP emailing me, & apologizing, I really don't want words, I I want actions, actions speak louder than words, & hellopeter, please stop thanking me for writing a positive review, it most definitely is NOT positive, VERY NEGATIVE, how do I give Pick n Pay zero stars???,GRRRRRRR Pick n Pay
