well, one CBP officer almost sent me to secondary checks because i had two US entry stamps within a week and a half of each other. why? because i went to europe from my own country and both flights (to and from) had layovers in the US. she said it was absolutely not common (which i doubt very much) and she was concerned i was coming and going because i want to stay (?!?!?!).
