This is slightly aside from the subject, but not too far.
A jeweler friend once made the inadvertent mistake of letting his
retail customer know who his supplier was for suchnsuch a thing, I
forget, doesn’t matter.
Customer goes online and finds out the jeweler’s cost on whatever it
was and insisted, rather vigorously, on being charged that price and
not a penny more by said jeweler who still would have to do his thing
to the article. He caved, worked for free, moans to me about it.
I fully appreciate trying to keep a customer. But my response would
have been to dramatically slide the item back across the counter and
say, “have them do it”. And I would have given that supplier a
freakin earfull.
So no, I don’t believe you’re too paranoid. In fact you are doing
the right thing, imho. Always play your cards close to the chest.
Reminds me of Ralph who worked for me many years ago. Cantankerous
Ralph. Image of Rodney Dangerfield in both appearance and manner.
Customer: Do you have ring guards?
Ralph: Yes we do, ma’m.
Customer: How much are they?
Ralph: Three dollars
Customer: THREE DOLLARS? Why so much? So and so jewelers across town
only charges me $1.50.
Ralph: Why don’t you go there then?
Customer: They’re closed right now.
Ralph: OOOH! Well, we only charge a dollar n a half when we’re
closed too.
Don’t get me started on Ralphisms. There’s not enough bandwidth.
