there is a tesco express 5 minutes walk away from my house, I go there quite often to get food.

There are 2 sales assistants there working either stacking shelves or working behind the till. They are both yes's and probably 4-6 yrs older than me. For the most part they have the numb bored look on them.

Whenever they are serving me however, when they see its me they suddenly start smiling the I'm all yours smile and giving as much eye contact as possible. And they have "the look" in thier eyes, you know the look. And when handing me my change they always make more "hand contact" than is neccesary.

Problem is what can you possibly say in this scenario, what can you open with etc.

I mean shop etiquette is you pay and leave soon as. And there is always a que of people waiting so I really don't know how to take advantage of this situation, or indeed, them.

Go direct. "Hey, I see you in here all the time and I think you're pretty cute." See how it goes.
