Couldn't find a more appropriate thread to ask the organiser collective.
I've had a rider send a brevet back with incorrect postage (meaning a trip to the GPO and £1.12 to be paid). Whilst trivial in isolation, this isn't the first time and, though rare, is starting to get on my goat.
Do any (perm) organisers out there not bother going to the GPO to pick up these? Or, if you do, how do you ask the rider to reimburse you?
