Closest thing I came was when I was shoping with my mum, we remembered an advert for a new fish shop that was near so decided to go. Straight away my mum tried to get me a job there, was embarrasing, she was making out I knew everything about any fish, and that it was my life. I may know something about fish, but I'm the first to confess I know little compared to some people I know.
Incidently, I think it may have been at the shop you now work at bogwoodbruce. Wish you the best of luck, you certainly know your stuff. and may even bump into you some time.
