Sold 100K USD systems to Faculty of Engineering from NUS. No commission (!) but I had the rare chance spending 2 days back in school. A lot changes have been going on there, small shops and restaurants here and there, new arts canteen (though I still like the old one more) and all young and unfamiliar faces.
My job there was actually quite easy – just supervising the installation process by a new colleague. My boss had told me earlier not to offer help unless something terrible happened. That was easy. I just stood there and occasionally sneaked out for juice break, coffee break, and water breaks after so many drinks.
