Is woolworths service going down !

I have always shopped at Woolworths, as the quality of your service is always excellent. You can return anything without being asked for slips or proof. Also when I have left potatoes etc on the check out till.....I have always been given a replacement. It is now such a stupid thing......but am so hurt. I bought at the last minute a shopping bad, a small one which folds up, as they never have stock of them anymore, and I am sick and tired of forgetting my 500 black cloth ones in the boot. I got home to find I could not find the bad I had just purchased. I was late in getting away for the weekend so decided I would deal with it when returning home today. I called the manager and she said no lost and found was handed in, and that she could not replace my bag that I had left on the counter. It is a tiny amount compared to the prices I pay each day, but it is the moral of the bad service of not having been helped by saying please bring your slip in for proof you did purchase a bag and we will replace it for you. Very hurt at not being believed and getting the service I expected from woolworths.
