'Hi there, I'm looking to purchase a compass'
The employee takes the Stupid Customer to the selection of compasses.
'Thank you, now...how do you actually work them?
'Well the arrow always points north, like you can see here...'
Interrupting Stupid Customer
'But where are we on the compass?'
'No no, it just shows you where North is....see look.'
'But, I want the compass that shows you where I am!'
Employee explains that the compass can't show this, then goes on futher to suggest she needs a GPS Reader. The Stupid Customer is determined she needs a compass and storms out the shop.
