They were so good that you just had to sing the song to them once and they got it. It's amazing. Sometimes it didn't come out the way you wanted but it was good.
I worked at an ice cream parlor called Chadwicks. We wore old-timey outfits and had to bang a drum play a kazoo and sing 'Happy Birthday' to people while giving them free birthday sundaes. Lots of ice cream scooping and $1 tips.
