Me again. This is my third deal with Frank, this time instead of me taking his old tat, he has just bought a bass from me and as with previous encounters he was a gentlemen and scholar* from start to finish. Due to Covid it's obviously not possible for another car park exchange right now so we've pencilled one in for some point in the future once Boris gives us the thumbs up. But Frank was adamant that he paid now, nonsense said I, so he slapped me about until I acquiesced. The funds were in my account very soon after.
*Visiting Professor of Scatology at the University of Ivor, in fact.
