Always check. Many years ago I had two new rear tires put on my daughters car at a major tire shop chain. They called to say it was done, so I picked it up from the shop, paid for them, and drove home before looking. To my shock, there were no new tires on it! Drove right back to the shop, of course. It seems they had installed the tires on some other car? They had no explanation as to why or how, but I got the two new tires I had paid for, and pronto too!
