I was at the gym last night chuffing away on the treadmill when a small child (she was about 9, 10 possibly?) jumped up on the treadmill next to me and just stood there for ages, not running/ walking with the treadmill turned off. Then her (i presume) Mum signals at me to take my headphones out, so I did and she asks me to turn on her daughters treadmill for her
. I stopped running, leaned over and obliged. Small child commences turning treadmill up faster and faster and faster.
Small child has bitten off more than she can chew and turned the treadmill up too high, and cant work out how to slow it down quickly enough/ cant reach the controls because she's so far back on the belt. She's clearly struggling and looked as if she was about to fly off the end so I reach over and whacked the emergency stop for her. Treadmill slows and stops, crisis averted so I look around and can't see her Mum anywhere.
Anyway, it appears small child had learned her lesson because she then commenced walking at a brisk pace and didn't turn the treadmill up again but at this point I'd totally lost my breathing and pace so had to stop. I was also sick of babysitting so got off and went home. On my way out, I ran into her Mum sitting in the cafe 
AIBU to think the gym is not really the place for kids especially unsupervised? On a wider note, if it normal now for 10 year olds to go to the gym instead of doing sporty outside activities?
dont have kids you can probably tell so I'm a bit out of touch, AIBU?
