We hired a Hawaiian guitarist for our beach ceremony. We were guaranteed that he would play loudly enough for our small group of 70 guests to hear him. However, he played very softly, and was not heard by many. We also asked for him to blow the conch signaling my arrival with my dad-he had difficulty, which we don't fault him for- everyone has "off" days- but by the time he could get a decent sound to come out, we were down the aisle. :-) It was kind of funny, so whatever.
