(Corrections requested) With convenience stores (7-11, etc.) trying to be gas stations, and gas stations trying to be convenience stores, whatever pump you pull up to, the business draws power and people.
24 hour stations are the normal here and are located just off a highway (101 or 280). Customers range from those with less cash on hand that only buy enough to get home (5 minutes at the pump), to those with large (puffy) trucks or SUVs that swallow 30+ gallons (15 minutes at the pump). (Average: 10 minutes at the pump for each customer). Midnight to 6 the customer count is less. Using a station I see when going to my local VA hospital as an example http://www.sanfrangasprices.com/map_gas_prices.aspx?z=11&lat=37.462992015873&long=-122.224724292755&sid=15611&tl=All it has two pumps at each of two islands, each pump can handle a customer on each side for a total of 8 customers at a time (they are usually always in use) https://encrypted-tbn3.gstatic.com/images?q=tbn:ANd9GcRsYDkH1F85Z2d7raR2yj45ADCgKmbnAkN6RDGgzrvxv-CFeJaj8w Plus there is power drawn for the mini convenience store as well as two fully functional ice repair-smog bays, each with their own car lifts http://www.kings76.com/var/m_8/89/891/216858/CACHED_288910-990-500.jpg I would guesstimate that the station has a 208VAC 100A circuit and in a 24 hour period is on average only using 50% of its capacity: 208VAC * 100A * .8 * .5 * 24hours = 199.680kWh per day. 8 customers every 10 minutes figuring they have half as many customers from midnight to 6am: 8 * 6 * 24hours * .75 = 864 So 200kWh used, serving 864 customers in a 24 hour period. 200kWh / 864 = 0.23kwh per customer in a 24 hour period.
