So, 2nd time out without my air boot on, very dependent upon my crutches.
I popped into our local supermarket, struggling with a shopping basket & crutches, got just a few items, & went to the 10 items or fewer desk.
Just as I'm about to reach the counter, (which also has the fags behind it), a woman sprints in from nowhere, does a slick sideways manoeuvre, puts her £20 on the desk & asks for her packet of fags! 
The woman serving apologetically rolled her eyebrows, but the ignoramus ordering her fags just grinned: obviously very pleased with herself.
Arrghhhhh! I was there with my loaf of bread, pint of milk, (any more is too heavy), & can of beans! This happens at checkouts again & again. What is wrong with some people!
aaaaaand breathe!
