Recently I realized my battery was corroding and possibly leaking. It was late afternoon on a hot day when I pulled into O'Reilly. Already occupying three of the other parking spaces were cars with hoods raised. Two associates leaned over engines in obvious thought. The third gentleman just needed advice. Yet Michael acknowledged us and came to our aid as soon as he was done with another customer. Together we realized my current battery was under warranty and saved me the cost of a new battery. Then, using tools they had on hand he helped me take out the battery, replace the drivers side headlight (which is behind the battery,) and install the new battery. the entire process took a half hour and he was courteous and helpful even standing in the hot sun. I was impressed and will continue to be a regular customer.
