It is snowing outside (Yippee - cold snowy weather - must be a UK summer on the way).
Chap has just walked in, undone his rucsac, spent 5 minutes emptying it, spreading all of his belongings around the floor, and making little piles of stuff. He then put on his waterproof trousers and coat, spent another 5 mins repacking it all neatly, and walked out again.
Not a word of hello, good bye, or may i use your shop as a temporary changing room / repacking facility.
Remind me again about how much I love my customers.
(and while we are at it, define a customer).
