When you receive an e-mail from Nigeria mentioning a business proposal and the intent to wire funds to you, the reaction is positively pavlovian:
Oh, that again. How many millions do I stand to make now?
This one, however, was different. The client on the other side of the wire really did contact me because he had trouble paying.
Looking into this account, I saw that he had succesfully paid before (through a friend abroad, as I found out later), he just needed a new connection this time.
It crept up on me how odd this was - A client who had gone through a good deal of trouble paying me before asking me what trouble he could go through now, to pay me again.
Not odd in itself, but in comparison to other requests:
Part of my job consists of trying, over and over again, to reassure prospective clients that it is a worthwhile investment of their time and money to go with my software.
Often times, the reaction is not curiosity or goodwill, but something ranging between the aloof and the mocking.
Alright, buddy, so you seem to think your software is good? Well, you better make sure I'll be happy on the other side of this transaction or I'll be seriously angry with you.
None of that was to be seen here.
