Without somebody directing behaviour, some people are lost. This thread has me reflecting on what I see done well at Costco gas stations here
- there is a single defined entrance, from there you fan into dedicated lines for a pump.
- pump hoses are long enough that they will reach the other side of the vehicle, at least for cars, and some trucks
- the lot layout makes it very difficult for somebody to parachute in to a queue
- they pay an employee to walk the lot at all times, dealing with any snags as they come up
- very stripped down islands - no squeegee, no towels, no groceries to buy
- a single defined exit. Only one way in, and one way out, unidirectional traffic
