hehehe... yeah Cas I have had to try to explain a few times when buying things what I wanted things for.... It hasn't bothered me to explain to strangers in shops because they are paid to think the customer is always right!!! LOL! Like today when I bought the plastic in bunnings for the bed and floor.... I think that was the last thing the girl expected to hear, but it did make clear what I wanted it for and therefore what I needed.
