Since I chucked the bics and started using a decent lighter from the cigar shop, I haven't lost one yet. Picked up a colibri firebird and extra fuel for under $20 and I allways get that thing back. When you hand someone a bic, they don't think twice about pocketing it. Hand them a cold peice of steel with an inch long blue flame and theyll stare at it and hand it right back.
