Sounds like many of our customers. Today my mate had this conversation.
Customer "Can I have some strimmer line please"
Baz "What size sir?"
Customer "I don't know, just strimmer line"
Baz "Is it petrol or electric?"
Customer "Erm, it's a strimmer, oh it's petrol"
Baz "What size strimmer?"
Customer "I don't know"
Baz "Is it a straight shaft or a bent shaft?"
Customer "I don't know, it's a strimmer"
Customer decides to go home and find out what it is, but just as he's leaving says "It curves down at the end"
Baz "So it's a petrol, bent shaft machine. You want 2mm line then."
It wouldn't be so bad, but probably 50% of our customers come in for parts without a clue as to what machine they want them for.
