Sounds ALOT like my 15 yr old!! At his age he be should more then able (maybe not willing) to do things like getting a drink, making toast etc. As far as things he should be doing, homework, feeding the dog, studying etc. I would definately make it a "game" of consequence. No video games today, friends over etc. You didn't do___ ___. Fill in the blanks. Kids are masters at taking advantage I think. Most won't do anything they aren't made to do! Lucky for you, two of yours do LOL. But most, won't. It's frusturating and you sound like a broken record. But with some kids thats just the reality. Make a reward system, or just a chart that he must get so many points, stars etc for the week or loses priviliges. And explain to him that being a family is TEAM work. And you and your husband rely on him and his sisters to contribute to the house to keep it running smoothly and keep everyone happy. Hopefully he'll get it!
