Does anyone have experience picking up/dating retail coworkers? I work in a large store with several HB's around my age (18-22) and want to know how to manuever from friendly chitchat to flirting to a date.

Well, if you've got the friendly chitchat down then that's a start. I wouldn't dwell on that for long. I used to work at a movie theater. Same idea I suppose. When one of my co-workers caught my eye, I would instead just start flirting with them. Dropping C&F every chance I got, making myself sound like I was qualifying her. If she started hitting me, or hitting on me, I took it as a good sign. I stopped having normal conversations and instead just flirted non-stop if it was reciprocated. Actually, if they start teasing you back, you have some interest in their eyes. Since you're already on friendly terms, you can actually get a phone number and move to text-game quite easily.

You have serious advantages here. You don't really have to worry about opening and you can make up ANY excuse to come talk to them. I also found plenty of time to isolate in these workplaces as well. However, I have to tell you now that dating people you work with can end in disaster. It's great, unless you break up terribly...

I do however envy your position here. Make good use of it.

Thanks for the help, I should have been more clear though. For the girls who I already flirt with and see that they have interest, should I just go ahead and ask for their number, or say something like "I'm going to X on Xday, you should come."? I do push C+F hard though, but have trouble transitioning from flirting/playfulness to closing.

You can actually do both in one sitting. Say you were going downtown to check out X,Y,Z some afternoon. You could invite her along and at this point here you could get a phone number since you'd have to have some way of informing them of the meeting place and such. Kills two birds with one stone.

It's what you do when you're on this "Date" that really matters. I really don't think you'll have much of an issue getting them to come with you since you've stated they already have displayed interest.

Thanks a lot, I'm going to try it out soon.
