If his native country is not the United States,
you may be barking up the wrong tree when you
bargain with him, because he may understand pricing,
bargaining and "a deal" completely differently
than you do. In Beverly Hills, there is a subset
of the population, with, yes, a particular ethnic
background (not the centuries-old stereoptypical
group), who will negotiate, set a price, have
the work done, then start to negotiate again.
This has led us to separate labor from any and
all parts and components purchases in order to
shorten the length of the hammer they can swing
at us....
