Sorry, but I have to side with the customer on this one. I've only been doing the retail thing for about 3 weeks now, but Kozy's screwed up. We had a charity ride 2 weeks ago, so everyone was in getting new tires for their bikes, and I probably sold 20 tires in 1 Saturday. Our policy is to discuss tire size, rim size, pressure, and tube size before handing over the goods. It only takes 2 minutes to go over those things before ringing up the sale.
He went in to get flats fixed, and Kozy's was eager to sell him some new tires too. The bike was there, so they had no reason not to explain why he got 2 flats, and what the correct pressure for the Armadillos was on his application. Labor cost for a puncture repair at our shop is $26. Yup, $26 to swap a tube. But you can be sure that the customer gets an explanation as to why he got a flat, and how it could have possibly been avoided. Of course, our mechanic gives the bike a quick going over to see if there's anything else that may need service too. The point is that this guy got sold tires, without any service.
