Is it important to you to be in a relationship where your partner is more powerful than you? You made it part of your post, which is why I ask. I don't see cashiers as lowly. It's a tough job handling people and $$ matters all day. If you want an unequal relationship then some of what you are posting is what goes with that territory. If, however, you love this person (whoever the person is) and this person loves you; love is the great equalizer; your opinion should matter fully as much as hers.
