I'm in healthcare IT and our hospital uses Vocera. One time our ER team was working a code and the MD triggered Vocera and asked it to call the X-ray tech. Vocera responds, "Calling... PIZZA TRUCK" It was this weird situation where everyone wanted to laugh but we couldn't because we were working the code. So our eyes all met awkwardly in the room as we collectively stiffled our giggles which the MD frustratedly cursed out Vocera. Meanwhile the actual ER tech ran and got the x-ray team.
