Lots of times I don't even get them lit before I decide I don't like them.
I'll try a few, usually. I force myself to try a lot of new stuff that I really don't want to.
If a cigar doesn't strike me as "good" after three tries, I don't go back.
If they strike me as "bad", they usually get chucked in the alley before an inch is gone.
Life is too short and there's too many good cigars.
