Brand loyalty IMHO is almost a one-way street, now-a-days!
I can't think of a corporation that has exhibited any true loyalty towards me in the past 5 years, or so...
Time was when you worked for an organization for a while you might feel some relationship that exceeded that of just a paycheck in return for your time & expertise.
I worked for Consolidated Freightways (and before that, 4 years @ Freightliner) for 10+ years, during which I saw it regress from being the top motor carrier in the US, a company known for a true organizational dedication to its employees, to being a hellish place to work, totally corrupted by the dominance of the finance/accounting beancounters. I got out (with my pension intact) and many of my friends and co-workers were not so lucky.
Brand loyalty to motor oil?
I like Chevron Supreme @ $0.59 per quart, Delo when an HDEO is indicated. I like Conoco semi-synthetics when I can get them for under a $. Amsoil products are excellent and I buy them when they are on sale/priced right.
Heinz catsup(ketchup?) is still my favorite!
Hellman's Mayo is Best Foods, East of the Mississippi, but Safeway Select is a better buy at $1 per quart...
Ruger. Kawasaki street bikes sinch 1975. I can go on.
Cheers!
