ClueChick: real clues from a real chick

Last month, I received this query:

I've had some fun with dating sites this year and moved onto trying to pick people up in the real world. Had successs on the two times I've tried - once was a friend of a friend of a friend in a pub and once picking up someone behind the counter of a shop.

In both of these, I had a the chance to make chit chat before I asked them
out. Easy and fun!

For my next amazing trick, I want to try meeting people who I only see for
milliseconds at a time - waiting for the lifts or in busy coffee shop. Hard
places to strike up any kind of conversation.

Do you think this is too direct:

Hi, can you tell me what your name is?
Uh, huh. My name is XXX. Are you a scary lawyer?
Thought so. Would you like to have lunch/dinner with me?

Or better to try and create some chat first?

I would love to have something insightful and brilliant to say, but I really don't. Mostly, I think this is a great idea, and I'm certainly getting a kick out of thinking about it!

Pros: It's playful, fun, lighthearted, and you don't end up spending a lot of time or effort on any given attempt before taking the dive and seeing if it goes to a date-like event.

Cons: It's pretty much a snap-decision sort of issue, so your personality (assuming you have one! which you seem to) doesn't have a chance to shine. I'm guessing that you're reasonably good-looking, though, if you're considering this sort of approach, and that will obviously help. Good grooming and a confident carriage also, obviously, are key here.

I'm guessing you'll get turned down a fair amount, but I wouldn't be surprised to hear that women took you up on this more often than one might expect on first blush. I definitely want to hear how this goes for you!
