The late (I think), great Alan Bodger of Gulf Aviation/Gulf Air would leave his office to fly the occasional sector, DC3 or F27, as Captain when needed; lighting up a fresh cigar was one of his taxying checks, so as to have it going properly for the take-off. Most FOIs (CAA) ignored it if they knew what was good for them, but one was bold enough to comment, whereupon Alan offered him one too.
