"20% deducted at the till - equivalent to the VAT"
So annoying people have no bloody clue on the most basic of maths.
OK, a note for the hard of thinking, and I really should not have to do this.
- Imagine something is priced at £1.00, plus 20% VAT
- That makes it £1.20 in the shops, at the till. The price you normally pay is £1.20
- Of that £1.20, the VAT element is clearly 20p
- Now, take 20% off the £1.20 at the till. 20% of £1.20 is 24p.
- That means you are paying 96p at the till, not £1.00
- Not equivalent to the VAT at all, in fact a better deal
