Petrol Stations and the bonk seem a feature.
I remember having serious bonk on a club run, we had done 40 mile to Skipton from Pontefract into a block headwind, when we got to the cafe everyone was tired so we had a longer than usual rest, when we came out the wind had changed direction so we had a head wind home ! some bright spark suggested we go via Blubberhouse, well it was carnage the ride was getting slower and slower everybody got the bonk, I got to 5 mile from home and had to stop at a petrol station (no shops open on Sundays in them days) I remember sitting with back against the wall forcing Mars bars (other chocolate confections are available) and pop down just to complete the 5 mile home.
