300g of cognac – almost 3 granite glasses? I don't know in what dimensions you live, but the classic granite glass has a volume of 250ml, the density of your cognac find out for yourself and count, but I suspect that two glasses will not get, right? This is first. Secondly, real punks drink before the concert, during the concert and after the concert (and also fuck schoolgirls after the stop) and absolutely do not get stuck with the transfer of alcohol into unclear containers. Punks Not Dead!
