When people are like that, its just plain rude. Yeah I brew, what do you do? Can I have some of that for free? You always have to have some sort of deal. You bring me bottles, cook dinner, bring cigars, wife swap!, whatever. Then you get beer!
Haha, but all jokes aside, I usually give out single 500ml bottles to people who are interested, or who have hooked me up. Last Christmas I brought about 10 bottles to work to give away. This spring I brough in 4L and some dixie cups to let the boys try it out after work.
The thing is, it costs money, and there is actual labour put in. Its a labour of love, so enjoy giving away a bit, but don't give away six packs unless the person deserves it, or its for family. Thats how I feel anyway. My friends own a shoe company, so I get discounts and they get beer, and similar deals with other gentlemen.
