My first day at work ends in failure

Description: It's my first day at work, and i'm working with a new team. i'm supposed to be checking their productivity, so i give them a short task to interpret.as soon as my stomach starts to hurt, i drink coffee to try to stop it, but it doesn't help. i start burping profusely, and my subordinates are surprised, but they keep working. more burps, and more humiliation from the team. this happens all the time. i feel incredibly embarrassed, and i have to stop working.
