If you have travelled through the NJ portion of I-95, and stopped at any service stations, you quickly realize how stupid this law is. A single attendant trying to fill gas for 10 cars. Drivers just waiting in line for 20 minutes to fill their gas!
I swear, I was the only person who would fill their tank and THEN park and go into the store.
Was a nice perk and convenient since I was going to park my car there anyway.
