Once upon a time as a developer for Palm handhelds I wrote an application in C which had to print via a Bluetooth printer.
When connected by wire everything was perfect, switching to BT it kept crashing for weeks without me finding the source of the problem.
Then came the day of my companies summer party. I've been the last guy to sit in front of the PC, investigating my problem, when at about 9 PM my boss came and told me, I should grab something to eat. So I went down, drank three beer and got back to work.
At about 9:45 PM the damn wrong * was replaced by the correct & and everything was fine.

I give software support to Rugged handhelds in a company and everyday some IT support moron comes to me with a crazy request. The day just started and...

IT Tech: "Hello, C, can you improve the touchscreen sensibility? It's not so responsive and sometimes we have to click more than one time to something work"

**breath in**

Me: "That's ok, the rugged ones that you have are very old, besides they have resistive screen, so your fingers won't do a good job"

IT Tech: "THERE'S NO WAY TO FIX IT? I guess I'll open a ticket for you to study more calmly about the issue"

**NGGGGGGGGGHHHH**

Me: "If it's not a software thing, I can't do that, I don't have hardware skills, I guess you'll have to call our provider about that, but, before you do something, try to recalibrate your handhelds, the majority of the users don't do that at the system's start and the touch experience really can become a mess"

IT Tech: "Hmmm, I'll try that, otherwise I'll back to you, thanks!"

OMFGGGGG

I am open to suggestions of a magic batch file/ .NET CF 2.0 software that will turn their handhelds into a Galaxy S6 touch experience. THANKS!

Coolest project was an order and billing solution for restaurants on Palm handhelds, written in C.
The cool thing was to completely develop the Bluetooth stack for communicating with printers for orders and bills.
This was the project to really teach me the diff between & and *.
Must have been around 2003, but I bet it's still running.
