Check your change on the self serve tills
I read online that the self serve tills occasionally give out the wrong change,coins fall behind the collection part and when they empty them they're never correct,people need to check their change so I've been checking mine,last week it short changed me 20p,I told staff and said they need to sort the machine but was only 20p and I had frozen stuff so I said forget it.Went in again today,same set of tills and it said I needed £2.05 change then gave me only 2p,this time I complained and it had actually worked it out wrong..my change was £1,02.Im now wondering about all those times i never checked and just put change in
