I was in the City today and found metered on-street parking. I was just going to drop something off quickly, and certainly didn't need a lot or garage. They have a new sort - one machine in the middle of the block - that prints a timestamped receipt that you place on your dash.
I reached into my pocket and had no quarters. [$.25/15 minutes] It would take plastic and I used my debit card. To be sure, I spent $.75. Later I realized that it was probably the least amount that I've ever spent that way.
What is the lowest amount that you have ever spent - and why?
