Companys think the extension is a sign of proffesionalism?

[DrkFusion]

I was talking to a friend of mine the other and he said that one of his clients, when he said he would code the management of customer information in php and index it using mysql databases. The guy asked him what the .ending would be, he did not understand so he asked?
"Pardon my ignorance, but what .ending?"
so the potential client answers
"You know, those .asp things that some big companies use"
so my friend replies
"Ah I see, it would be php"
So then the potential client asks what is php, and they get into discusion about this.
Then my friend told me, that the potential client said this.
"I want this to be proffesional, I have been to many sites, and they have the .asp ending, it makes there site and background of there site look proffesional, can you do the job in the .asp?"
So my friend (not wanting to loose a customer, said sure, so what he did was set up .htaccess and rename the file to .asp (as a joke, because he did not want to put his full potential and effort into a work, when it wouldn't be appreciated because it didn't have a certain extension) and format php, though he was not hired, as one of the employees said that it was php.

Now what do you think? I think its completly absurd that people might think asp 'looks' proffesional, I am not sure, it does not make a difference to me, but I need input on this, is this guy crazy, or is this a common thing between companies hehe.

I found this a bit funney while my friend was telling me this, as the issue of the extension implying a certain reputation to the company really did not trigger any discussion before.

If anyone else has had similar funney events share them please
