[Quoted] Are you sure this is a good idea? I just imagine a customer calling:
"Good morning. This is ACME Corporation customer support. How may I help
you".
"Good morning. We have an issue with our last order. The order number is
12345".
"Just a second, let me look this up. Ah, yes, I see. What is the problem
with the 50 anal beads?"
"Anal beads? This is the Jesuit Convent of xyz and I am calling about
the order for 30 rosaries!".
