i'll smoke it through unless the effect is too adverse (i.e.-- gives me that pre-puke feeling! lol).
i've had several cigars start out being "eh-- so-so" or downright UNgood at first and then get really nice as it smoked on down. for that reason alone i'll take a cigar at LEAST past the half-way mark.
if it's a gift, i'll try to make it to 2/3 even if i don't like it. like someone mentioned, i hate to be wasteful, and i especially hate to let a gift cigar go without giving it every chance. i assume the person who gave it to me saw something good about the cigar and wanted me to enjoy it similarly.
well, except smelly4tay, as we all KNOW that all HE gives out are pure dog rockets! (i shouldn't even HAVE to tell you all that i'm kidding!). 🙂
if i purchased it, i feel that i've more entitlement to trash it if i don't enjoy it by the midway point.
