Honolulu, HI
I came in to get one flat tire either repaired or replaced and left with 4 new tires, as one check after the next revealed serious problems with each of the other 3. The salesman who assisted me (sorry, didn't get his name) was unfailingly friendly and courteous. When he saw my dismay at the news that there was a thorn in the 4th tire, and it too needed to be replaced, he said he would throw that one in for free. All of the service guys I interacted with took care to see that I understood what was happening, step-by-step. On the whole, except for the large and unexpected expense, it was a very positive experience.
