Do you live in a rural place with a small, connected community? That's the only way your "promotions" would have had any impact. I find it hard to believe that posting on social media single-handedly saved that business. I find it much more likely that people started getting more acquainted with the new reality of the pandemic and after re-budgeting started buying food at places where you get lots of calories for cheap (like Little Caesar's).
