STOP OVERCHARGING NON-ALCOHOLIC DRINKS IN PUBS

I'm quitting drinking and have not had a drink in 2 weeks and saved £70.Today I bought a pint of coca-cola which was £1.90 in the Red lion a pint of beer 4.8% is only £2.08 and a pint of shandy is £2.04.Everywhere else i got shandy i paid between £2.40 to £2.90 and A pint of Carling starts from £2.70+.If you think the price of these non-alcoholic drinks is disgusting sign and share the petition.
