Hahaha, My experience about Lulu too, the cashier at counter#7 charge 460 QR over bill. At first they try to say it difficult coz I have no bill for referrence. But, I ask them to look at the credit card slip they mention all everythings, time , date counter# why don't you track in your system to see how much I really buy? I explain them how to make it easy way. After the found out what I said is right, they try to excuse said the that new staff make mistake!! whatever!!! I finally got back cash 460 QR , Thank God!!!
