I used to work at this company where like 3 guys took care of basically everything. All but one of them, let's call him Rob, eventually left to better companies. About a month after that, my team had to deal with a pretty big issue and we were having trouble coming up with a solution so this idiot had the brilliant idea to page Rob. As if the poor guy hadn't spent the last month doing the job of 3 people who were already doing the job of a 5 people each. Rob got online, said "Why did you page me?" and immediately left before getting a response. I liked Rob.
