What shall I buy?

I have a rule...in fact I have many rules. But the one that's important here is that if I ever get a parking ticket or something of that ilk, whatever the fine, then I will spend the same amount on a treat. I think it's the ideal solution to combat the immeasurable depression that's brought on by the thought of having to donate yet more money to the wasters that occupy many a town hall - with immediate and abject apologies to the public sector staff that do provide a genuine service to the community.

I think I mentioned a fortnight ago, a tenant managed to get himself from here to the States without a valid passport, meaning I spent my Saturday finding a key so his sister could get into the flat and FedEx his passport to him. On my return journey, my phone went, and I pulled over thinking it was the sister who had a problem. And therein lies the problem. I hadn't realised I stopped in an empty bus lane. As evidenced below.

It's cost me £60 (reduced from £120 for good behaviour), so I need to find a £60 treat. And convince myself that in future I should do anyone any favours. At all.
