I played an early morning round at Canadian on Sunday morning, in the wet (the weather wasn't nearly as bad as it looked)... By the end of the round my feet were soaked. I was wearing Footjoy AWDs, which carried a 1 year waterproof warranty. I knew I bought them near the start of last year, a year during which I only played 20-25 rounds. Had I played 50-plus rounds last year, I don't think I'd have been returning the shoes... I'd have felt they had served me well, as I rarely ride, and play in all conditions, and therefore my shoes usually take a pounding... but considering my low-round total, off I went...
As soon as the sales doode at GT, Jarred, who sold me the shoes last spring, saw me, he asked me if everything was ok with my shoes (this, before I mentioned anything, and before he could even see I was carrying the shoes)... This was impressive. I'm sure he's sold one or two pairs of shoes in the past 12 months (he works mainly in the shoe dept)... so remembering me was a surprise.
I soon found out he remembered the brand and color I had purchased. I told him about the wetness issue, and told him I didn't have a receipt. Not a problem, if I had put this on my leaderboard account I was told - which I hadn't. (My GT peeve - why do the cashiers not ask you if you're a leaderboard member when we make a purchase? I've noticed this a few times in the past year - I've either had to bring it up, or I forget to - It is my responsibility to do so, but... anyway, kinda odd).
Off Jarred went to dig for my reciept in the non-Leaderboard archives. After about 20 minutes, he came back with my reciept, from, as it turns out, May 15, 2005. Before he showed me the receipt, he asked me if I remember buying anything else that day - I did - a dozen ProV1s, and an Ashworth pullover or some such. This, for him, confirmed that the reciept was mine, and we were good to go. $129.95 worth of validated credit was mine.

Kudos to GT and specifically Jarred, and his manager.
