While I agree that this a pretty ridiculous reason to walk out of a restaurant, I do expect wait staff to have a grasp of the beverage menu. They are expected to understand the beer menu regardless of their pay. That said, I'd be willing to bet, because she already admited that she didn't know...
And didn't get her number in the process. Though, that's probably a common occurrence if he's calling a woman a ***** because of something stupid she said about beer.
Use Chrome Remote Desktop to access your desktop or laptop. Not really helpful for the OP if they're going to get rid of the old computer, though. But, about the only think I do regularly with my 8 year old desktop these days is run Beersmith.
I use the Lite version of the Android app for the calculators and brew day timers. I just store my recipe for the day in the cloud. I still use the desktop version for recipe formulation, even going as far as to access it with remote desktop when I'm on my Chromebook or tablet.
