What a joke!

Why is it that when you buy a keg of beer, you have to give them your drivers license, tell them how old you are, fill out paperwork in duplicate, sign your life away stating that you will not be serving to minors and pay crazy $ for a keg deposit plus a tap deposit? All the while, there are two guys spending $3000 on hard booze for some birthday party, bragging about how they are going to party until people get alcohol poisoning, they did not even get asked for their ID???? What a joke the laws are in this area..... OK have a nice day....
