Auto Mechanic Coffee Mug - Do the Noise Again. Slower, With Hand Motions

Do the noise again. Slower, with hand motions. One side of this mug shows the customer waving both hands at the counter while the mechanic takes notes; the other shows the clipboard alone, its page covered in carefully drawn sound waves.

Keep it on the toolbox or the service desk, or give it to the tech who can tell a rattle from a hum. It suits auto mechanics, service writers and shop teachers. The design wraps an 11oz mug.
