This is some simple shit, but it's something I do all the time, and something other people seem to have trouble with.

In at least the past ~10 times I've gone to bars, I've gotten some drinks from girls, and got drinks bought for me by guys. It's something I like to do most of the times I go out.

I love alcohol, so this kind of shit is important to me. Maybe it's not as important to you, but if you find yourself in a situation where you don't want to spend money but do want to get drunk, you can do what I do. It's not a special "trick" or anything, but I know a lot of guys don't do this.

When you're at a bar, you need to make friends with at least a group or 2. Also try to make friends with at least a few random guys throughout the place. It's easy-peasy. Just be friendly, positive, and provide value to the guys. You can talk to a guy about pretty much anything- you can trade stories, or just act really interested in whatever shit he says.

This has a few benefits for you. It's social proof- girls might see it and become interested in you, or you might get invited somewhere later on, whatever. You're also canceling out a few potential AMOGs.

Most importantly though, if any of those guys feels like spending money, there's a decent chance they'll offer you a drink. This is doubly true if you make friends with a group and somebody's paying for a round of shots. They'll most likely offer you a shot, and if they don't (motherfuckers), let em know you'd like one in a friendly way. When I was in Cali, I met up with this rich guy on vacation whose main goal (it seemed like) was to pay for whatever I wanted. I was just friendly with the guy, and he paid me back by paying for half my shit that night.

With girls, don't be afraid to ask them to share a drink. If it's a mixed drink or any beer you haven't tasted (you can just pretend it is), it's fuckin fool-proof. Be friendly and outgoing, ask what they're drinking, and whatever answer they give, give them this look like you're curious as to what it tastes like and ask for a sip (or straight-up say "Let me get a sip"). I've been turned down a number of times, but it usually works out. If you get turned down, tease them about their phobia of germs or fear of strangers. If they let you drink some, don't be afraid to take a huge gulp (be playful about it). Basically just be playful and friendly with it, and they'll be cool about it.

In terms of "seduction," it's somewhat insignificant. But it works as an opener, it can work to build attraction if you're cool about it (it's a pretty "bold" move), and in a way, it kinda builds comfort (if she's cool sharing her drink with you, she's probably gonna be cool when you push forward). I usually do this with multiple girls (really just depends on the size of the place).

And with guys, like I said, they'll be cool with you and a lot of times they'll invite you to after-parties and shit.

Mainly though, IT GETS YA DRUNK!
