They can turn you away for any reason , and they will if they ' re afraid a case could be made that they ' re doing something wrong . I just came home for Thanksgiving break , and I turned 21 earlier this month so I stopped in a grocery store to get some alcohol . When they asked to see my card they wouldn ' t let me buy alcohol because I still have the vertical ID . Apparently even if the ID is valid and the date is correct , the grocery stores in my area will refuse to sell you alcohol unless you also have the horizontal ID . Good thing liquor stores and restaurants aren ' t as stingy about it . <| sep |> I think the karma should probably be based upon the ratio of your own rebuy cost to the victim ' s . For example , if you kill someone in a sidey with your anaconda , you should be penalized more .
