beatbox at the gas station

I needed gas this morning and while it pumped I noticed the air supply station -- it was turned on and while people were fussing with their tires, it was dealing with its air supply by releasing some air in increments, making for a very distinctive beat box sound! I don't have the skill, but someone with such skill could have easily done a little rap or ditty with the air supply behind. It seemed to me to keep very good time, while I was listening. Sometimes it is the smallest observances that are the most delightful.
