From bad to terrible

Ok so I kind off got used to the poor shopping experience at Pick me pay Walmer park in PE die too long waits at cash out due to cashier's slow service but today was just on a different level. So pick no pay are having a special on 2lt milk whare the pack 2x2lt mils in a bag in their fridge thus making it buy one get one free. So I arrive at the all mighty check out cashier number 4. Lol so this cashier ask me is it buy one get one free. So I informed her that since it has been packed together like that I assume it as but she should be fami**** with their promo's. Next thing the cashier as me did I pack the 2 x2lt milks in the bags myself. Where in your life have you seen that. I told her that if she is fami**** with what was going on she would see that they are already packed like that in the fridge. What does she think...did I then sneak into their bakery department and took one of their bread bags and just decided that I'm gonna pack 2 in a bag and place then all in the fridge and then pay for one in order for them to think it's a special
