i like your post/suggestion(s)
regarding
take-time to chat wit 'em

HOWEVER,
don't do it
if there're touri$t
in the area

do it only if it's just you & the vendor,
and NO tourists within 30-yards of their booth/shop/what-ever
....'cause if there are touri$t$ in the area, and you ain't $pending, then you're a di$traction

plus,
sometimes
they might not wanna be bothered,
and
want to relax and/or chill during a touri$t lull

.
.

for example,
with me
my *visits* with a few of my vendor-associates are FREQUENTly interrupted, when a tour-bus or van delivers new-blood to one of the craft markets.

NO time to chat with me
