How to get French customer service

So I'm at the huge olive counter at the big fancy gourmet grocery store (located in the mall...whatever.) They have something like 30 bowls of various olives - you can ask the person to scoop you however much you want of the olives. Pretty neat, it allows you to get a bunch of different types of olives...since my dad is coming in town tomorrow, I thought it would be kind of cool to get a bunch of different kinds of olives and let him do a tasting.

Big fancy gourmet grocery store olive counter...nobody in the area but me and the lady who scoops my olives...and she's on the phone. No worries, I think, I'll give her a minute. 5 minutes go by and I come to realize that she's on a personal call and no matter how many times we've made contact she isn't getting the hint.

I try picking up the scoops and stirring the olives, then look at her - I obviously want something here right - it's not a self-service set up here. Nothing.

I wonder if I'm allowed to taste the olives before buying some...good question, I'll ask the attendant, once she gets off the phone.

Eye contact, nothing...

So I figure what the hell, and I stir a bowl of olives, get one on the spoon by itself, pick it up with my fingers and eat it...then head to another bowl. THIS got her attention...before I could make it to the second spoon she was off that personal call and asking how she could help me.

AAAAHHH - so that's how you get their attention.
