I went to pick n pay today to buy eggs today, to my surprise when I start to prepare the eggs they were spoiled, then i went back to their shelfs to look if they have good eggs but to my surprise all eggs were spoiled, then i took a picture for evidence then i went to the cashier who was very helpful nd I explained my problem and told her that i lost my slip but as you can see all the eggs in the shelfs are spoiled i asked to speak to the manager who was not available then i was given eggs that were at the bakery and they removed all the eggs am happy that i was given good eggs but my concern is that if it was not me who noticed that the eggs are spoiled they would have continued to sell them to people who don't have an idea about the quality of eggs i am not happy at all thanks.
