A stranger approaches you and whispers, "Hey? Can I interest you in some medical equipment? Cheap." He then proceeds to open his trench coat. You are relieved to discover that he's not an exhibitionist, but is merely peddling his wares.
"Look at this baby! This is a Shimadzu Prominence-i | LC-2030C Plus Liquid Chromatograph | HPLC System. Top of the line. Only $18,950. Waddaya say? Eh?"
You do not respond.
"Okay, I can see that you are a sophisticated customer. Can I interest you in a GE Optima CT660 128? This one's gonna cost you. It is $285,000. Come on! You won't find it cheaper anywhere else."
You show no interest.
"Alright, then. I won't waste my time on someone who does not appreciate my goods." He leaves in a huff.
