It might slightly disturb traffic between 11:00am-1:00pm on a weekday as people stop by for lunch but outside of that, I can't imagine it'll make too much of an impact on traffic.

Even late night (midnight - 3pm) I don't imagine it turning into the Shockoe Exxon or anything.

The Wawa up the street is mostly dead at night [as opposed to the Wawa on Midlothian that can be overwhelming (and overwhelmed) at night]. Even the Sheetz on Midlo never gets really wild at night or on the weekends (maybe because everyone is across the street at Cook Out).

I can kinda understand just generally not wanting a giant gas station at that intersection in terms of creating a more human-scale, pedestrian-friendly neighborhood crossroad but it doesn't really seem that intersection is really heading in that direction in the short term either way.
