(long time lurker in the sub, really find the posts neat. came across a problem a few days back, thought i'd see your guys's input)

So asking out waitresses isn't anything new.

They come to your table, and you're given ample opportunities to make small talk, escalate etc.

Now some may say it is in poor taste to approach people during their work -- which I believe is a whole different issue to address. But, if there's a girl you'd hate to just pass up, you wouldn't want to just idly sit back like a nervous little shit and become all emotionally constipated in hypothetical "what ifs". You'd act upon your interest. You'd strike a conversation and make your interest known to her (whether it's a yes or no, it's your job to ask and hers to reject/accept).

But how the hell do you find an opening for a hostess?

At this one restaurant she's constantly busy, sitting tables and such. She doesn't wait on tables and is continuously occupied with her job. No openings to strike conversation.

I walk into the restaurant, she asks "how many", I give her the number, and she hurries to seat us, and goes right back to seat the next person in line.

(The restaurant is really busy and she only works the lunch rush)

I don't want to force a conversation when she is obviously swamped with work.

I sincerely can't figure out a way to approach this girl.

How would you guys go about this scenario?

some additional facts

I know the waiters there quite well, since I'm a regular. I know them and they know be by name. She's a new hire who only works one day a week during lunch (really weird hours imo). She seems busy and even stressed often by the workload -- once I had like 30 seconds to talk to her due to a seating error on her part and she didn't seem too abrasive. We're both Asian, it's clear English is not her first language.
