Normally staff in the Dumfries store are polite and helpful but the last twice I have visited I have been sadly disappointed. The first time I queried the order in which the use of my points offers were used therefore making one invalid and was abruptly told 'it wouldn't matter which order I put them in as it's now less than £5'. It would matter because if she used them in the order I gave them the first one would have been used prior to my balance being less than £5. The second visit I queried the shelf offer buy one get one half price and was told it was not for my items in a dismissive 'the till is correct' manner. I asked if they could move the ticket which had been placed in front of the wrong item & was ignored by the young man who checked it and the till operator!
