I see what you're saying and I'm kinda the same way but I will respect a line if one is formed.
I view it as a dispute between the employer and the employee.
I do not view it as a dispute between the employee and the customer (me).
As a customer of a product, I buy/replinish the product when I need/want it, not when an employee wants me to buy it.
If I go to buy the product when the employee is upset at his employer, that is not my problem. If the employee then scratches/spits upon/blocks my car as I pull into the parking lot then clearly the employee does not want me as a customer . . . except at his personal convenience. His convenience is no concern of mine.
My concern is to fullfil my needs and the needs of my family.
So if I go to get my legal product, when I need/want it, and I am thwarted by a group of disgruntled employees, then the likelyhood of me EVER GOING BACK is slim to none. F'em. They injure me (my car, my ability to shop, etc) and I have no problem injuring them (by no longer buying said product/service). Now if the employee chooses to kiss and make up with his boss, he may still end up out of a job because of the way he treated me.
Its my money, I will spend it as I wish, and I choose to spend it at stores/with services that value me as a customer.
