Plenty of Muslims around the world today do stuff they are not supposed to. Heck,none of us are without sins! But I know, even from my past experiences, that many non Muslims like yourself find it still kinda shocking/disturbing to find Muslims indulging in things that are so widely known to be forbidden for them. Guess with time it will simply grow on you that not everyone who claims to be a Muslim will adhere to their religion 24/7.
