It took me a few dozen phone calls to find a pharmacy with thermometers in stock.
I ended up getting a thermometer (the last one in stock) from a pharmacy 20 minutes away by motorcycle from my place (Haarlem).
What if we create an app where people can add requests based on their addresses, and other users can browse those requests and reply/attend to them.
Maybe someone nextdoor have a spare thermometer.
Maybe some other neighbor would be willing to borrow one.
