Many cars only come with the inflator repair kit now. It would have been nice if they let you know. That being said you can use the kit or buy the spare. The kit only works for small holes in the tread. If you damage the side wall or have a blow out you will need to have your car towed in for a new tire. An actual spare should be required by law but it is not.
Should have check first bc the place is full of ways to rip you off. Go back and demand them to give you a spare.
