Has anyone financed a street vendor cart for a Thai?

yes....

street vendors....

motor cycles....

som tum on 3-wheeler....

kanom-varn on 2-wheeler and 3-wheeler.... etc

if they already have their bikes.... the financing of another 20,000 thb would get most of them on the road to entrepreneurship....

if they start from scratch.... the cost of used bike plus contraption on wheel.... would come to around.... 50,000 thb

i do sincerely hope you would find it in your heart to finance and help out several worthy locals.... so they too can enjoy true democracy and better their own daily living and life experience with their family members et al....

May the Almighty God bestow multitude of blessings upon you continually.... so you will in turn bless others along your life sojour.... cheers

I "donated" a sa ling to my brother in law.

6000baht for an old Honda Dream and another 4000 for the sa ling including fitting. That was about 4 years ago and it's still going strong.

Can't kill those little Honda engines, it still amazes me...

You have to be very selective, know their business well and collect repayments DAILY - walking there are getting it in cash.
