Awkward

You know when you are walking around in a store and can't find something? Then, you finally find someone with a work shirt on that can help? You make small talk all the way to the area of the store that carries what you were looking for and then you thank them and part ways.

But then, you keep passing them...over and over...while you complete your shopping trip.

Are you supposed to acknowledge them every time you see them now because you are "friends" or do you completely ignore them as if you'd never met? That just seems rude:)

Hmmm...it's just awkward.
