These Shoes.... BOGOF?

My girlfriend and i went into Great Yarmouth for the day, not long after we'd started seeing each other. It was her first time in the area and for some bizarre reason i thought a day in town would impress her. DOH!!!!
Our first stop was at a well known and very large shoe retailer. A quick look around told her there was nothing suitable for her and we wondered towards the exit. As we did we passed a very excited man in his 20's holding a shoe obviously from the display. as he went to pay the assistant was heard to ask;
"Do you want the other half of that pair"?.
Anywhere else that would have been either insulting or just plain stupid. But not here.
"Oh, yes please" said the happy chappy.
Off trots the assistant, returning a moment later with an identical shoe. Totally identical. The same style, same size and in fact the same foot as well. On a shelf full except for 1 gap, she'd managed to pick up a left shoe to go with the left shoe in the customer's possession.
Fortunatley she noticed before her customer did. Unfortunately not before my girlfriend did, who started shaking with supressed giggles. As everyone does in this situation, we hung around pretending to look at shoes whilest we followed the rest of the conversation.
"Nearly gave you two left shoes then"
"That's ok, my feet are the same size"says the innocent prospective shoe owner,"Can i pay by card"
"Of course you can"
I've already written about the way credit cards are dealt with in Norfolk....
And true to form the customer handed over his plastic. And walked off. (Perhaps he'd filled with petrol at the same place i did??)
The sight of the slightly plump shop assistant chasing her customer out of the store holding a credit card shouting "you only sign a piece of paper, you don't leave your card here" was wonderful entertainment, particularly for my girlfriend, who was a born and bred Londoner.
Couldn't have been too bad for her though, I'm pleased and proud to say she's my wife now.
