I agree, a business owner has a right to place whatever restrictions he likes on his services. A business decision of course, and as an owner of a service company (no, mot making MKIV's and QV's) one I understand . . . though one I'd personally make differently.

It's kind of like if a business owner said, "If you want to do business with me, you have to sign my 'exclusivity agreement' promising not to do business with anyone else for the products and services I offer". Does the owner have a right to do that? Sure! Good business? Not so much. One might get away with it for a while if they have an exclusive, single source product . .. . but it's not really in keeping with the principals that make capitalism such a great system. In the end, it's bound to aggravate some customers and maybe turn some away.

Better that customer loyalty be earned through surprisingly excellent service and good value. Coercion shouldn't have a place in this.

I imagine it's not easy making a living with an unseemly group like glider pilots as one's only customers, so I have deep appreciation for all the honest and hardworking businesses that strive to serve us while keeping their families fed at the same time. Gotta be a labor of love.
