Had Alec paid for sex? A few times when he got out of Mantecore, but then he realized there were a lot of women who would sleep with him for free, especially if he charmed them or if he had enough cash around. He enjoyed strippers a lot better because they were true artists.
"Somehow I doubt you'll see me." He knew there was a bounty on his head and he doubted anyone wanted to wait to hear the 'I'm a different Alec' argument. Plus, from the sounds of it, they were kind of the same person minus the sleeping with Mary Winchester part.
"Alright, suit yourself. Just, uh, I don't know. Hydrate or something, man. You look terrible." Alec knew it was drugs and the lack of supplies and this dude didn't have the benefits of genetic manipulation, but still. Woof.
