Milk Tart...Gone Sour...

I went to l checkers at about 10 or so...10:14 on the 06/09/2020,as the till slip says paid almost R50 for two milktarts...just to get home after a great supper...to eat milktart that taste sour...and on top of it, gifting the other milk tart to my friend...that's like a slap in the face...why sell old ****...I once also wanted to buy a slice of cake at the bakery,the lady even advised me I quote " don't buy the cake it's old".If it's old remove it...stop selling stale things to your customers...hence your'll removed the white coated spheres that had an expiry date...please do the same with the old rotten cakes...
