it didn't ! had an episode at Hayes store 10 days ago - all I asked for was a £5 note for some change in my pocket. First customer service lady didn't have any which is fair enough and then second Lady greeted me with 'What For !' I even had another customer offer support suggesting she should try a more apologetic approach and all I said to her was she should maybe be a bit more friendly - 'well that's your opinion' I must have had a handful of times after then being told about store policy that they don't do change. Before I know it I turn round and there's a security guard in my face pulling some kung fu move ! I have of course complained and get told a load of rubbish about its just one of those things and it's just six and half a dozen of the other. What For is in my opinion too blunt not a great reaction to any question from a customer - all it tells me is that Sainsbury's don't really care that much about their customers at all. First one of these I've ever written in my life and I only turned 50 last year !
