Glad to see it still happens...
Back in the days when DOS was prime, and windows software was in the up-and-coming stage, I was testing some corporate windows (win16) software.
Under normal conditions, windows was run in the autoexec.bat, but I tried running the windows software under a DOS prompt anyway (I was bored and had time on my hands, so sue me).
Where I was expecting the standard "this is a windows program" message (forgive me for paraphrasing, this was a long time ago), instead, it went along the lines of "this is not DOS software you fucking moron".
While this may have been acceptable for shareware of the time, it wouldn't cut it for corporates on the off chance they want to have a "play" with their computer. These guys pay a rediculous amount of money for the software, and bucketloads more for the data feed. No really, the fees are just plain fucking scary. So no, callilng them fucking morons was not on, these guys have heavy duty lawers on the payroll for normal day to day work, so taking us to the cleaners for a "funny" statement would have been a breakfast snack to them.
I did report the "bug" to management. I suppose the programmer responsible who thought it was funny at the time, would still have a sore arse today. Whoever it was, sorry dude, but I can't let something like that slide. No matter how funny *I* found it. :-)
