Unfortunately, this one has happened more than once. :/
Out on a group ride with friends...I wear my gear all the time...they don't. So...they are standing there waiting after a fuel stop as I gear up....get on the bike, reach down to turn the key...to discover the key is NOT in the ignition, it's in my pocket.
Lots of swearing and name calling as I remove the gauntlet, get the key, put the gauntlet back on and ride away.
