Answer:
If the owner of the station wants to meet more customers who buy premium gas, he should be around the station:
on weekends.
Explanation:
Most luxury cars are driven on weekends than on weekdays. Another reason supporting weekends is that luxury cars require premium gas to function at higher fuel efficiency, to maximize their speed and performance, and to avoid their engines knocking. Finally, most luxury cars are driven by chauffeurs than the owners on weekdays. Chauffeurs are not the real customers because most of them buy gas on charges to their companies' accounts.
