I occasionally pass through Buena Vista as I travel to visit folk back in Ohio. However, I have only stopped in the BP up near I-81 and the Exxon station with the Burger King there on Rt. 60. I have not ever had any issue OC-ing in either of those spots, but I may have only been in each while OC-ing once or twice.
**Just remembered, I have once eaten at the Ruby Tuesday in Lexington while OC-ing and had no issues whatsoever.
