Yet, if you fill up with £40 of petrol at the petrol station (something you might actually need a VAT receipt FOR), you specifically have to ask for one. Doesn't matter if it's Tesco or Sainsburys petrol, or one of the smaller chains. You still have to specifically ask for a VAT receipt, adding to undue delay in the queue.
What is this bollocks all about? If a supermarket prints VAT receipts by default when you buy a pair of jeams, a DVD or a bottle of whisky, surely it isn't much to ask for the same supermarket's petrol station and indeed every other petrol station to print a VAT receipt by default as well?
