I have found Jamaicans to be a patient people but not when it comes to money.
It is hard to convince someone to make $1 one hundred times with the expectation of hundreds of more times rather than make $100 all at once and hope the chance will come again.
There is a saying in the Cockpits, "You can shear a sheep many times but you can only eat them once"
Many struggling businesses look at Lenbert and the One Love Pub Crawl as the Messiah coming to save them once and not to return so they want to "eat" it now instead of growing a new, steadier "sheep shearing" business.
Just my opinion.
