Would you pay to audition speakers

A dealer told me that he will let people audition 1 pair of speakers for free. If you want to hear multiply speakers
he charges 500.00. If you buy a pair of speakers he will credit you back the 500.00. He says he does this so people don't waste his time. He says If someone is serious about purchasing speakers they won't have a problem with the 500.00 deposit. I'm Interested in knowing how the Audiogon community feels about this.
