DS 15 seems to enjoy a few beers and sometimes vodka with his friends. Doesn't come home pissed but has obvs been drinking. He is honest about what he drinks but he worries me. He is a big lad, over 6ft, and gets served in the coop and news agent. Don't really know what to think!! Pretty annoyed that he gets served and thinking of speaking to the manager in the shop. Bit what's normal??
