Just playing devil's advocate:

If I've bought a BBQ and hamburger-adjacent equipment, I probably prefer my hamburgers home-made.

I might view the ad after 7 PM, as that's when I get home from work, and still decide to go there the next day during my commute.

Engaging with burger-related activity might also mean that I run a competing joint, so advertising to me is pointless (unless you want me to buy that one time just to check my competition).
