was yelled at work today when i had a major block

was yelled at work today when i had a major block i had to relay a question from a customer to my manager since it was my first day and i was clueless as hell about menu items and questions surrounding those items. i tapped the shoulder of a coworker who has been working here for quite some time. at that moment, a block came one and i was just standing there, with weird facial expressions, trying to get the words out. they then yelled, "what? what? WHAT? WHAT IS IT? SAY!" in an impatient tone and it shocked me. heck, it shocked me so much to the plint that my block disappeared. i felt really shitty for the rest of the shift.
