Pub & Restaurant Prices for Alcohol Free Beers & Soft Drinks

Being a non-drinker I am saddened to see that people who do not drink, may be because they are driving are penalised in both pubs and restaurants with extortionate prices.  We all know that soft drinks prices are exploited for something which does not have any 'alcohol tax' on it but can cost as much as a beer which does. For example a 275ml bottle of Becks Blue can cost cost similar price for a pint (568ml) of alcoholic beer. I have paid over £3 for a bottle of Becks Blue which means I would normally have a cappuccino coffee because it is cheaper or similar price.
