very cool of the guys at that shop! I would have been the same way w/ no helmet. Plus my son would NEVER let me live it down! The kids around here rarely wear helmets- except mine of course. My law "if it has wheels and your on it, there MUST be a helmet firmly attached to yor noggin".
Once he was playing up the street so I grabbed my bike to go up and get him. Well since it was only a block I didn't bother w/ the helmet. BOY did he give it to me, and I have to say... he was right!
