I owned a gun store, not a sporting goods store, a gun store for over fifteen years from the late seventies to the mid eighties. If you came in my store and didn't have complete control over your physical body, including your extremities, I would politely tell you "NO" you can't handle my firearms, let alone try to purchase one. I now work as a senior range officer at local shoots and if a shooter approaches the line with visible tremors and shakes I won't let him un-case a handgun, let alone load and fire one. Sorry. I fly private aircraft and if I can't pass a physical I lose my license. To fly while "handicapped" with a physical problem is to endanger myself and those around me. I don't blame the store owner and doubt you could prevail in any "discrimination" suit. Use your head for a moment and lay aside your personal feelings. If you can't keep a loaded pistol pointed in a safe direction due to a handicap, why would you even want to posses one? Yes, you have rights but like many others you forget that those come with responsibilities. Be responsible and think seriously about this experience. I'm sorry you have a nervous disorder. I'm not sorry you were denied the "right" to force a store owner to sell you a firearm.
