StuF I buY

Spotted this motorcycle petrol ration book at a market a few months back and forgot to buy it however I was talking to the vendor a while later and he knew he had not sold it but was not able to find it but as luck would have it he tapped me on the shoulder last week and the book had turned up,I didn,t forget it this time and bought a hair cutting kit also so no excuses for looking rough at the TT .Why do I buy this shit I don,t really need ?
