iCod - completely off topic but
If you want to avoid licencing laws and you want to make a profit ycan't you sell bags of crisps (or something small) for say £1.50 or £2.00 or whatever and give a glass of pimms/alcohol away with the purchase.
That way you set a price but you aren't actually selliong the alcohol, it just comes free with the vastly overpriced piece of tat you you have picked up from the cash and carry.
So for example at at christmas you sell the mince pie and give the glass of wine free with it but the price of the mince pie is calculated to cover the cots of both and to make a profit.
