I worked with a bloke a few years back who was asked to bid on a contract to supply about £1.5m worth of IT equipement and services to the army. He refused on relgious grounds say it was against his religion to support violence or war and his concious wouldn't allow him to supply equipment and services to a military organisation. Very odd i thought, someone else bid, won it and it was worth about £40k in commission to them over the term of the contact.
