There are several of these for me. It took me months before I plucked up the courage to serve myself and pay by card at the local unmanned petrol station. It couldn't be simpler!
Things I have not yet achieved include:
Inflating tyres at the petrol station.
Selling on Ebay (I buy all the time).
Going through a car wash.
Negotiating some junctions where I have seen accidents or near misses. I use longer routes to avoid the area.
What situations do you avoid?
Is it me or am I getting mixed messages
