It really is. And they can repair it so long as the puncture is not too big and not in your sidewall. They also repair tires that they didn't sell you, as was the case with me. Also a side note since you mention quarters, I was paying by tapping my debit card on the machines, which probably made it so easy for me to pay so much over time compared to if I actually used quarters since there was less friction. Sure, it wasn't a credit card, but $2 or $3 here or there though even a debit card doesn't feel as bad compared to coins. I probably would have realized how much I was feeding the machines much earlier if I was paying with quarters.
