Best practice for delivery to cars

Holidays are inevitably busy for fast food restaurants especially "driving" holidays like Labor Day. When all things work according to plan, a customer is able to obtain their fast food from the drive thru shortly after paying and pulling up to the window. However, when this isn’t possible, fast food employees are often directed to tell the customer to pull aside and wait for an employee to deliver to the car. Though this can be an operational necessity it does expose them to additional exposure they would not face just being in the store. As such, you should take due care to develop procedures and to train for the safest way to perform this duty.

Consider dedicating a parking space for this specific incident and make it one that would prevent your employee from having to enter into the traffic from the parking lot. For instance, some stores have spots which are close to the back door or along the side of the building. If such a spot is unavailable, make sure the employees instruct the guest to pull in somewhere where both they and other driving guests have clear line of sight.
Normally, employees are in a rush to get back into the store and may be tempted to jog/run. However, when speed is increased, they are more likely to see pavement or floor conditions which then result in a slip and fall. As such, running/jogging in general should be discouraged.
The same actions which keep the sidewalks and parking lots safe for the guests will also help employees as well. This includes periodically surveying them for cracks, holes and other defects, clearing debris, ice, and snow, and blocking off any areas which are in disrepair until they are able to be remedied.
