I work for a background screening company. There's only one way a company can find out where you worked without you telling them and that's by pulling your credit report. A job you worked one day will not be on your credit report. Also, most companies will not comment on rehire eligibility...
Doesn't guarantee they'd do them right (to where people would actually want them).
Stained glass dunks were fire and still go under retail. Most people only buy what's popular. Unless SB becomes popular nothing will matter.
