wow we're getting high brow around here.
I bartend Friday and Saturday nights, and would not be able to finish a robo on the way to work. I'll purge it when I get there, let it go out, and re-light it after work 4.5 hours later. Is it a perfect example of the cigar? No, but it's fine for me considering it's 2:30 am.
I have gone to dinner with some guys here, and we show up at the restaurant with sticks still burning. They get set in a safe place and re lit after dinner. I'm not letting one sit in an ashtry for 2 days or anything, but if you're tossing a cigar after 30 minutes of it being out, then you are wasting half a cigar.
