If I was allowed I could leave 0 stars to waitrose, mean and xenophobic staff at Waitrose Sidcup for using my vouchers @I was told that the electronic vouchers are universal(by a Bromley manager )!I have been using them for a over a year ,but today they decided that I could not use them because they said it is their decision (even though the scanner accept it them)!I have spent hundreds of pounds last few year in this overpriced store and from today on I am boycotting this store!They made me feel cheap and they were very mean, the store manager and the cashier!I would not ever set my foot in their stores and for sure spread the news on every platform!People don't you ever buy anything from this store ,they don't deserve your money!
