Actually, we have two spots (that I know of) in Newark and Wilmington Delaware where you can take your bike to, use their professional bike stands and use their tools. No charge, but they ask for a donation. Mechanics will not do the work (except when dealing with a Child) but will give advice.
BTW...There is or was a restaurant in Virginia Beach called the Great Steak where you chose a steak and had the option to cook it yourself on a huge indoor grill with an array of spices and sauces at your disposal for no charge. No, you couldn't bring your own, but the place was excellent and very very busy.
Oh geez. A 0.001% exception. I think you understand the point.
