What is so hard about giving good service?

[Eric Adams]

"the company is gonna wait till the customer complains (which 100%
they do)..and by the time all this time from shipping the wrong part and
customer complaints..the part they orginally wanted would usually be in
stock...then ready to be shipped..."

Why not just tell the customer up front that the part is not in stock, and
spare the anger and grief, and the potentially damaging customer relations?
Make the most business sense to me.  Once the customer has been through so
much trouble, chances are they are gonna' take their business somewhere
else, along with their loyalty and satisfaction.
