I've been going to bars alone for the past 3 weekends since at present I don't have any friends to go with me and I'm trying to be assertive in my desires of wanting to casually get laid and the bar was a popular suggestion to me. The issue now is what can I do to up my chances at the bar when I don't have any friends with me? Especially since I'm aware coming with friends and having fun is the best way to look like an appealing guy...
