I did actually also comment on the sale of tabbbacco products and alcohol at sainsbury by minors it is common law ( in the U.K, U.S.A.(were some states the legal age for alcohol is 21) Aus, Ect) that nobody under the age of 18 sell or purchase these products, sainsbury already requires that anbody underage were the customer wishes to purchase said items call in a cashier of the legal age to complete the transaction i mearly stated if this is already the case would it not be simplier to have check outs for the non sale of these items as to make it easier on both the customer and the cashier this allowing for muslims who do not wish to handle the sale of alcohol as well.
