After noticing my tire pressure was low if pulled into Kal Tire on Jamsyl Drive in Windsor. I did not buy my tires there and have not been there before. Assuming I had picked up a nail or something I explained this to the young man at the desk who was very nice and said they would take a look. I waited about 20 minutes until he called me up to the desk. He explained that there was a hole and that they had put a plug in it. When I asked how much I owed him he said noting, they were happy to do it for me and hoped I would consider Kal Tire if I needed tires in the future. I definitely will. What a nice surprise that was.
