Jeff saw there was a bar option, and as it was the first option that Jeff saw that could potentially get him alcohol the quickest and potentially for free. So he set the bar option and put it on... his closet door. Along with making it so his stuff would be in some cupboards in the bar itself. That would include his clothes, some games, and some other junk he kept in there. Then he entered in and saw a nice well lit bar with nice wooden tables and chairs, the bar table seemed nicely polished with a handsome man behind the counter with a distinguished vest and moustache who was polishing a beer mug.
The bartender glanced at Jeff and said "I believe you are too young sir... Please age a good few 5 years." Jeff was confused for a second until he hit a small growth spurt and then looked in the polished wood and saw he looked a bit older. It wasn't a drastic change, but noticeable.
"Cool!" Jeff said "Can I get a..." Jeff's knowledge on alcohol was... limited... "Beer..."
The bartender raised his eyebrow and then went to the tap to pour out a beer with just the right amount of foam and... Jeff took a sip and found out quickly he didn't exactly like beer. The bartender started chuckling a little at Jeff's inexperience/distaste and Jeff left out with a huff. He'd be back... with his girlfriend... and maybe with knowledge of some cocktails or something... The 21 year old walked out and shrunk back into his 16 year old self, giving anyone a few hours to wander into his closet... Although who'd be wandering into some teenage boy's closet?
