dancergal said:Car flirting is just that. It a quick moment in time that you can say "you're a cutie" and not have any strings that might be attached to it, like in a face to face flirt.
Along the same lines, occasionally I'll take a book or other purchase to be rung up, and admire, say, the unusual hairstyle of the cashier. No interest in making her wary of a weird customer, though, so I hold the verbal compliment until after paying, when I'm about to walk away.
