One of my millionaire-maker ideas:
To lease space at IAH for a smoke shop. If one makes a tobacco purchase, then one may proceed to the smoking area. Without a purchase, one could access the area for $2.
I think it would be a HUGE hit for pipe, cigar, and cigarette smokers.
I'm a cigar man, and everytime I'm through IAH, I get angry that there is no area set aside for smokers.
