You're just upset because Christians have the secret to Life Eternal and The Truth, and they're right and you're not, aren't you?
BTW, too bad you aren't a Jew, because you could have sued the shit out of the c-store chain for religious persecution. I mean, you would have felt threatened and demeaned, and you'd have had your civil rights trampled and all, because of all the stuff the cashier was saying. Oh, wait...I'm sorry...its everyone else who is persecuting the Christians these days, right?
I've got to get straight with The Truth.
