Read the large, bolded print

Client: I didn’t want XP - I wanted Vista.

Me: But you asked for XP.

Client: But I want Vista now.

Me: I’m sorry sir, but you signed the form - it says right here in bold letters that there is no return on software.

Client: I only signed it. I didn’t read it.

Me: Again, I’m sorry - but it’s in bold letters for you to pay attention to it.

Client: Maybe YOU should pay attention!

The client than grabbed the form from my hands and ran out of the store.

Three minutes later, he came back in silence.

Client: …I left the CD

He then apologized and returned the form.
