referring to the above spares conversations; you lot are lucky I am not about to relate my experiences selling spares for brit bikes in the 1970s/80s.
Some of the types I used to deal with drove me to the very edge of my tolerance and sanity to the extent one day I shut up shop and flogged the lot off.
I'd believe you...I worked in a bike shop as well running my own thing for 17 years...You meet all sorts and much as I'm a fan of variety and eccentricity it can be 'challenging' sometimes!...Ian
