i did something i shouldn't have at work

today was one of those days when everything went wrong. my boss asked me to put together a fancy drink for this big client meeting, and instead of getting it right the first time like i should've, i mixed up all the ingredients. ended up with a brownish mess that looked nothing like what was on the menu. i knew they were watching from behind the counter as i struggled, trying not to panic too much, but deep down, i felt like i failed big time. it's so embarrassing because everyone here is counting on me to get these things right. still can't shake this feeling of dread every time i think about it.
