@bro. yeah you can do that in a bar. I've never had a problem. Buy a drink, take a taste before you buy. If its weak, throw the bartender a twenty and top it off right in front of her. She'll get the message and either hook up with a free drink (you still throw her cash for a tip) or make your next one strong as fuck. never failed.
God'll prolly have me on some real strict shit
