Walk instead of drive thru

When you are picking up food, going to the bank or even filling a prescription, park your vehicle and walk inside instead of using the drive through (aka drive thru).

Every time you use a drive through, you burn about 18 cents worth of gas idling your car. According to Quick Service Restaurant Magazine, the average drive through wait time once the order is taken is three minutes.

Parking your car and getting out also allows an opportunity to stretch your legs.

Some people have argued that drive throughs save on energy because they allow establishments to have smaller dining areas (or eliminate them altogether.) But others question such logic. If enough people declined to use drive throughs, new facilities would instead be designed with walk-up (and bike-up) windows.
