The reason for that is because choosing whether you want a receipt is a pretty new thing, presumably to somehow appear environmentally friendly. Until a few years ago most places used to give one by default and if you didn't want it you were expected to just put it in the bin on your way out of the store.However, the voice asking you if you want a receipt in the near-ish Sainsbury’s Local is a different one and is almost apologetic.
Most supermarkets in this country except Waitrose and the Co-op use NCR self checkout machines. I think there must have been some kind of software update by NCR to facilitate the asking for a receipt, as every chain seemed to get the feature at about the same time. Around the same time they seemed to also get a lot more freedom with the visual design of the interface, which is a shame as I thought the stock NCR one was quite good and the new ones are a bit rubbish. A few shops are still using the stock one (or maybe it's an older version), including WHSmith and M&S.
In Asda, it asks if you want a receipt but still reminds you to take your receipt even if you ask not to have one!
