The person you replied to said
after I had 5 years to freeze dry enough shit to trade for concubines.
and you indicated that your sister would have enough of her own freeze-dried food that she wouldn’t need to trade for it. Thus, she is safe from being OP’s concubine.
My experience with Whataburger is that the food is mediocre, and if it weren’t for bad service, they’d have no service at all. In fact, there’s one Whataburger that I have failed to eat at twice because no one came to the counter both times I tried.
