Look, I'm all for using normal situations to talk to women as I think your odds go up a ton when she doesn't feel like you're just there to hit on her. But if the line is moving so fast you don't even have one minute, then it's probably not the place to do this.
If you have several minutes(like at Starbucks), you should probably see what she's doing right after she gets her drink(staying or leaving). If staying, suggest you sit together. If leaving, you know you have to hit a point of asking her on a date in a short period of time before she gets her drink and has to go.
