The issue here is not the price, it's who is being allowed to buy the booze and where it is being drunk. As far as your post is concerned, the only crime being committed here was littering on your doorstep. You do not know who bought the booze or in what condition the person was drinking it, it may not have been a kid and quite possibly in a sober state.
I see from your previous posts that you dislike Valentines day and have a very good powers of perception in identifying all the condoms around Exmouth. May be you wish to live in a booze free, sex free, partner free environment, like a commune. As a hard working couple my wife and I enjoy a drink at home, with everyone feeling the pinch savings anywhere are a blessing. Why should I be penalised in paying more. Parents need to take charge of their youngsters and the town needs strict policy on drunkenness, shops can also help by not selling to youngsters, next you will be telling me I can't spoke outside. Why should you or anyone else dictate how much I decide to pay for a product, it's my money, I earnt it and I am responsible, those that aren't need to be dealt with but AFTER the event.
