Tires & Nails

So I thought I would update you guys for those that follow me on fetlife as well. Found out Saturday that I had a nail in my tire. I had an inkling thursday, because my tire warning went on but all my tires were pretty low, so I didn't think twice about it and then Saturday night it came on again and I figured it was the plug that I put in before. Nope, a nail and inches away from the first plug I put in. So I bring it in Sunday to Costco where they tell me they can't repair it because of how close it was to the plug and they don't have my tire in so I have to wait till tuesday or wednesday. So I call up today and ask if they got it in and they tell me no but to check in around 3 when another truck will come. So I wait and try to call up and no one answer, so I decide in all my stress to take a nap and try calling back at 430, now they won't even answer the phone and when they finally do they put me on hold and disconnect me. Yay...talk to Costco in general and not just the tire center and they have to walk over with a message. They finally call me back and I ask if they got the tire in and the guy is like no, and they're being shipped from south carolina it seems even though I was told it would take 2-3 days. He finally stops and goes, can I put you on hold while I check something...ok... he comes back after 15 minutes and says, "oh seems we have 20 in stock and got them yesterday..." He tells me that if I come in it'll take them no time to put it on and I don't need a reservation. Well...it did take them no time to put the tire on, it took them 2 hours to start though as I roamed around Costco without a membership, at least I got a hot dog out of it, although they no longer have onions which sucks. Why is my luck so bad with service people?
