Life- Bike tire change

I'm not good with machines. The cars are a similar story.

In the end I found another shop and had the guy also repair the lamp, put a new tire, and readjust the gear shifter, all operations that go usually a bit like this: I know how it's supposed to work, but when I try, I take ages, never works the way it's supposed to, and makes me angry. So screw that.

I do believe that air chamber patches making an air chamber airproof again are an urban myth though.
