We only ask two things.
1. Referrals are a courtesy
Mechanic and tire referrals are sent as a courtesy only. SQP does not guarantee their work — only the services SQP provides directly: truck washing, diesel and batteries.
2. Keep your area clean
After you have people work on your truck, please clean up your area before you leave for the day.
