Ugh. My (first) stepmother used to work for Kraft back in the 1970’s and she brought home a bunch of crappy flavored peanut butters that sat in the pantry for 2 years while my father insisted he wouldn’t buy any peanut butter until the stuff was eaten.
It took him to divorce her before he started buying me my Jif. Not knowing or caring what went on their relationship, I think the banana-flavored peanut butter alone was grounds for divorce.
