Oh boy....you just reminded me of a funny story of a passenger who has known-digestive problems but thought it was a swell idea to eat a burrito in the terminal right before departure. Oh, the fun that ensued on THAT one! I was sooo glad I was working aft position but felt bad for the front FA AND pilots who nearly had to don their oxygen masks for about 30 minutes while we pulled in and out of the line! Apparently, other pilots were wondering what the issue was and hilarity ensured when they told them.
